I am researching [http://reu.mscs.mu.edu/index.php/(i,j)-step_competition_graphs ''(i,j)-step competition graphs''] while attending the ten-week Marquette REU; my mentor is [http://www.marquette.edu/mscs/facstaff-factor.shtml Dr. Kim A.S. Factor]. I will, initially, be doing background reading with Carissa Babcock and then we will branch into our own research questions. As my research becomes more personalized, I will contribute more to this description. My weekly log can be found below.

This project focuses on expanding the theoretical applications of [http://reu.mscs.mu.edu/index.php/(i,j)-step_competition_graphs ''(i,j)-step competition graphs'']. Specifically, this project explores an extension of the (''i,j'')-step competition graph from [https://en.wikipedia.org/wiki/Directed_graph digraphs] to directed hypergraphs (hyperdigraphs)--objects whose arcs consist of two disjoint (and possibly empty) sets, the tail and head set (see figure). After establishing a definition for our extension, we will investigate its innate attributes concerning its construction and applications. As the project progresses, results are finalized, and the paper is ready for submission/publication, more details will be added.

I have included three main artifacts from my REU at Marquette University. These were produced at the end of the summer and the paper is still being edited before we (Dr. Factor and I) submit it for publication. I have placed them here instead of at the end of my lengthy research log, which you will find below.

I spent most of this week preparing my presentation; therefore, my reflection focuses on it. I had a breakthrough on creating simple hyperdigraphs in LaTeX without wild packages, though it is still a pain, which is nice. I created my presentation using a beamer class and scripted it, which I feel was helpful. Concerning my presentation's quality, I'm still waiting for my feedback. In terms of improvements, I feel I could drop the introduction to graphs and digraphs; I think those two slides don't help me. Instead, I could spend more time building the foundation for my definition. I could also improve my conclusion; it feels very rushed when compared to the rest of my presentation. Overall, I think my presentation was fine but has room for improvement.
  
 +
This past week was not very productive regarding my research. That is, I spent so much time focusing on my presentation that I didn't end up doing actual research, a disappointment. I have so many ideas and questions regarding my definition. Hopefully I get to do some next week.

I am doing this reflection late because I intended on working over the weekend. Instead, I got distracted studying for the GRE Mathematics Subject Test. Anyways, this week was fairly productive. I completed an abstract for submission to the Young Mathematicians Conference (YMC) at Ohio State University (hopefully I'll be accepted); I prepared an outline for  my paper and am working on filling it in; I also began preparing my poster and am working on filling it in. Hopefully, I can get all of my paper and poster done (to the extent that I can right now) and focus solely on math. I am currently working on a uniqueness theorem and characterizing my new definition.

I did a lot this week but accomplished very little. That is, I submitted my abstract to the Young Mathematicians Conference, and I polished my poster outline along with my paper outline, too. Completing these three tasks was nice, but they, ultimately, do not mean much if I don't produce enough results. That's why, over the weekend, I completed a proof of a theorem and outlined my proofs for two others. Now, as exciting as this sounds, my definition is, essentially, such a natural extension of Factor and Merz's (i,j)-step competition graph that my proofs follow an almost identical structure to theirs; while this situation makes producing my results incredibly simple, it takes the fun out of it. Hence, I've become a little bored concerning my actual research. That is why I intend on exploring the competition number of hyperdigraphs and showing the NP-completeness of the construction of my object. The former will provide a challenge while the latter is merely interesting.

This past week consisted of accomplishing major milestones: I filled in my paper and poster. Establishing the body of my paper required finishing my theorems, and completing my poster followed. I spent most of my week observing my extension of Factor and Merz's paper. That is, I played with what constructed the body of each theorem, and I discovered the reasons behind their paper's structure. I found how they implemented a "story" into their mathematics and told it through natural mathematical progression. I feel I can now delineate between learning mathematics and developing it--though these actions are not mutually exclusive.
  
 +
Despite making significant progress in my REU milestones, I was rejected from the YMC. I did not expect the YMC committee would accept my proposal for a talk but, if they had, it would have been a nice surprise. I suppose I could try submitting an abstract to another conference but I think I would rather focus on (hopefully) publishing a paper.

Nothing interesting really happened this week. This week and next week are either presentations (poster/powerpoint) or preparing for presentations. Hence, I mainly polished the materials I had. Meaning, I made small tweaks to my poster; I worked on some new theorems to add into my paper at a later date; or I practiced my presentation, among other things. I am slightly nervous for the poster presentation because I've never done one before. I've written papers and I've given presentations but I've never done anything related to a poster. However, seeing my poster printed and how well it turned out calmed that anxiety. Lastly, I FINALLY completed those ethics training assignments. Overall, I'm hoping next week goes well!

I don't have much to say. All of my presentations went well. Yes, I wish I could have changed a few things but those changes could only happen if I had more than ten weeks to conduct research.
 +
Regarding my time at Marquette, I had a wonderful REU experience. I loved working with my mentor. I discovered a lot about graduate schools, writing mathematics papers, ethical research, and delineating between the development of mathematics and teaching/learning it. I would absolutely do this again.

Project Description

Here is an example of a directed hypergraph (hyperdigraph) I created.

This project focuses on expanding the theoretical applications of (i,j)-step competition graphs. Specifically, this project explores an extension of the (i,j)-step competition graph from digraphs to directed hypergraphs (hyperdigraphs)--objects whose arcs consist of two disjoint (and possibly empty) sets, the tail and head set (see figure). After establishing a definition for our extension, we will investigate its innate attributes concerning its construction and applications. As the project progresses, results are finalized, and the paper is ready for submission/publication, more details will be added.

My weekly log can be found below and after it, you may find my artifacts from the summer.

Background Readings

I felt having a list of the background reading I am doing would be helpful. Hence, I have created one below. These readings include the ones Dr. Factor gave me and the ones I have found. Note: if a link is missing, the reading is either from a textbook or I was unable to find one.


Artifacts

I have included three main artifacts from my REU at Marquette University. These were produced at the end of the summer and the paper is still being edited before we (Dr. Factor and I) submit it for publication. I have placed them here instead of at the end of my lengthy research log, which you will find below.

    • Please note the paper is still in progress and will be subject to periodic updates until completed.

Project Log

This is my daily log for what I accomplished. Each day includes an estimate on the number of hours I actually worked on the project or in Cudahy. My activities may include updating the wiki page, attending working lunches, meetings with Dr. Factor, working on various projects with Carissa, or configuring printers; that list is not, by any means, exhaustive. Note: the end-of-week reflections are the last things I do on the last day of each week before I leave the office, naturally.

Week 1 (5/30/17-6/2/17)

Day 1 (5/30/17)

  • Attended MSCS REU orientation
  • Met with mentor, Dr. Kim A.S. Factor, and began discussing project details
  • Dr. Factor and I discussed goals: having BioMath: The Biology and Mathematics of Food Webs done by Thursday and reading The (1,2)-step competition graph of a tournament (by Kim A.S. Factor and Sarah Merz) by next Wednesday
  • Completed pages 1 through 30 of BioMath: The Biology and Mathematics of Food Webs. I plan on finishing the packet tomorrow and seeing how far I can get through chapter 3 of Applied Combinatorics by Fred S. Roberts

Day 2 (5/31/17)

  • Attended library orientation
  • Finished the BioMath packet.
  • Began reading The (1,2)-step competition graph of a tournament
  • Began reading chapter 3 of Applied Combinatorics.

Day 3 (6/1/17)

  • Attended a talk on good research practices by Dr. Kim Factor
  • Filled out direct deposit form
  • Met with Dr. Kim Factor and drafted the milestones and discussed moving our lunch with Carissa to Wednesday
  • Reviewed milestones and compared them to the program's google calendar
  • Printed additional readings for the weekend
  • Continued reading chapter 3 of Applied Combinatorics
  • Continued reading The (1,2)-step competition graph of a tournament

Day 4 (6/2/17)

  • Uploaded a pdf of my milestones for the summer
  • Worked on chapter 3 of Applied Combinatorics
  • Continued reading The (1,2)-step competition graph of a tournament
  • Began reviewing other papers
  • Created project's Wiki page

Reflection: End of Week 1

Concerning my research, this week was relatively uninteresting. That is, I spent most of my time trying to find literature (beyond what Dr. Factor gave me), working through background readings, and finding a good work area. Of those three tasks, I spent most of my time on finding a good work area (it was my top priority); I can happily say I completed this task. I cannot wait to really dig into my research--make it past the background reading.

I accomplished my goals for this week. I attended various meetings, orientations, and finished the BioMath module, among others. I intend on furthering my research this weekend. Specifically, I hope to read multiple papers and complete chapter 3 from Applied Combinatorics. Next week, I'll be meeting Carissa on Tuesday, and we'll finally discuss the material Dr. Factor gave us; I'm excited.


Made during Week 2 on Day 3: I was told an hour estimate for each week would be nice. I worked approximately 40 hours this week (I did some stuff on Saturday to make up the missing time from Monday).

Week 2 (6/5/17-6/9/17)

Day 1 (6/5/17)

  • Got in around 10:30AM
  • Finished reading chapter 3 from Applied Combinatorics
  • Created a LaTex document where I am writing my notes on Applied Combinatorics--a link to it is here, please note it is still in progress
  • Created a LaTex document for teaching Carissa TeX
  • Configured the printer in room 410
  • Finished formatting my personal wiki and began a rough draft of the project's wiki
  • Confirmed a meeting with Carissa tomorrow, 6/6, for 8:30 AM before the ethics training.
  • Left around 3:30 PM, estimate for the day is 5 hours

Day 2 (6/6/17)

  • Attended meeting with Carissa at 8:00AM
  • Attended ethical research training at 9:00AM
  • Handed off Applied Combinatorics to Carissa for reading on Graph theory
  • Began reviewing The (1,2)-step competition graph with Carissa at 3:15PM
  • Made note to include approximate total number of hours in end-of-week reflection
  • Left the building at 7:08PM, will be back in two hours...Didn't make it back to Cudahy, finished at the apartment. Estimate for the day is 13.5-14 hours

Day 3 (6/7/17)

  • Got to Cudahy at 9:00AM, discussed various definitions with Carissa
  • Lunch with Dr. Factor around 12
  • Received The (1,2)-step competition number of a graph by Factor, Merz, and Sano for reading and began reading it

  • Began creating examples for our examples pdf (they will be added tomorrow)
  • Drafted potential research questions
  • Left lab at 4:40, time estimate is 6 hours

Day 5 (6/9/17)

  • Arrived at 9:00AM
  • Finished making examples pdf with Carissa
  • Began formulating definitions for generalization
  • Began presentation for the meeting with Dr. Factor on Tuesday
  • Began file with BibTeX citations on background readings and paragraphs detailing what they were about
  • Finished formatting background section for project's wiki page
  • Left around 4:20, approximate time for the day is 7 hours

Reflection: End of Week 2

During this week, I worked on reading papers, teaching Carissa LaTeX, and formatting definitions. I met Carissa on Tuesday and our working partnership has been going well. We are good at catching each other's errors and talking through our confusion, if any, regarding various concepts. We made significant progress on finishing the wiki, setting up where our research will go, and are getting ready for our presentation with Dr. Factor on Tuesday. Our research is going well, overall, but could be moving faster.

For my personal research, I have some working ideas. I am turning over a few ideas for various generalizations regarding this project. Dr. Factor would like some working definitions, and I intend on giving her some on Tuesday. Over the weekend, I will work on cementing my some ideas into something more concrete and read other papers concerning hypergraphs. I am very excited at the prospect of proving theorems and actually working on math. If she wants it, I intend on helping Carissa find a general direction to go with her research question, if she doesn't want to join me. That all being said, I only have ideas and no actual thought supporting them; I have what my professor, Sean Raleigh, would call a "highdea."

My hour estimate for this week is 41 hours.

Reflection: End of Week 3

This week, I started interacting with mathematical objects. I worked on my generalization a bit, and I stumbled across some other interesting ideas. I am now looking for definitions concerning hypertournaments in lieu of k-hypertournaments. I'm currently looking at the paper Dr. Factor gave me to look over; it is very dense but at an appropriate level. I have a growing interest in hypergraphs and their colorings. I wonder if I could combine the coloring of hypergraphs and my generalization. I feel as if my "highdea" is becoming more concrete. Lastly, Carissa and I have officially split up, in terms of research questions; she, however, if interested, may join my project. I plan on finishing the edits on that paper before Monday, preferably by the end of tomorrow.

My weekly hour estimate is 36 hours.

Reflection: End of Week 4

This past week did not feel very productive regarding my research question. I determined my definition is new and interesting enough for pursuit. I also figured out the question regarding whether or not it is NPC is rather simple; hopefully, I'll have a proof by the end of the week. I have also produced enough questions to pursue over the summer. These questions concerning my definition are as follows: is it really just a layering of (i,j)-step competition graphs; is its construction NPC; does it have a universal competition number; are there any algebraic connections to this layering at direct products (another 'highdea').

My weekly hour estimate is 38.5 hours.

Reflection: End of Week 5

I spent most of this week preparing my presentation; therefore, my reflection focuses on it. I had a breakthrough on creating simple hyperdigraphs in LaTeX without wild packages, though it is still a pain, which is nice. I created my presentation using a beamer class and scripted it, which I feel was helpful. Concerning my presentation's quality, I'm still waiting for my feedback. In terms of improvements, I feel I could drop the introduction to graphs and digraphs; I think those two slides don't help me. Instead, I could spend more time building the foundation for my definition. I could also improve my conclusion; it feels very rushed when compared to the rest of my presentation. Overall, I think my presentation was fine but has room for improvement.

This past week was not very productive regarding my research. That is, I spent so much time focusing on my presentation that I didn't end up doing actual research, a disappointment. I have so many ideas and questions regarding my definition. Hopefully I get to do some next week.

I am doing this reflection late because I intended on working over the weekend. Instead, I got distracted studying for the GRE Mathematics Subject Test. Anyways, this week was fairly productive. I completed an abstract for submission to the Young Mathematicians Conference (YMC) at Ohio State University (hopefully I'll be accepted); I prepared an outline for my paper and am working on filling it in; I also began preparing my poster and am working on filling it in. Hopefully, I can get all of my paper and poster done (to the extent that I can right now) and focus solely on math. I am currently working on a uniqueness theorem and characterizing my new definition.

Reflection: End of Week 7

I did a lot this week but accomplished very little. That is, I submitted my abstract to the Young Mathematicians Conference, and I polished my poster outline along with my paper outline, too. Completing these three tasks was nice, but they, ultimately, do not mean much if I don't produce enough results. That's why, over the weekend, I completed a proof of a theorem and outlined my proofs for two others. Now, as exciting as this sounds, my definition is, essentially, such a natural extension of Factor and Merz's (i,j)-step competition graph that my proofs follow an almost identical structure to theirs; while this situation makes producing my results incredibly simple, it takes the fun out of it. Hence, I've become a little bored concerning my actual research. That is why I intend on exploring the competition number of hyperdigraphs and showing the NP-completeness of the construction of my object. The former will provide a challenge while the latter is merely interesting.

Weekly hours: approximately 38.5

Reflection: End of Week 8

This past week consisted of accomplishing major milestones: I filled in my paper and poster. Establishing the body of my paper required finishing my theorems, and completing my poster followed. I spent most of my week observing my extension of Factor and Merz's paper. That is, I played with what constructed the body of each theorem, and I discovered the reasons behind their paper's structure. I found how they implemented a "story" into their mathematics and told it through natural mathematical progression. I feel I can now delineate between learning mathematics and developing it--though these actions are not mutually exclusive.

Despite making significant progress in my REU milestones, I was rejected from the YMC. I did not expect the YMC committee would accept my proposal for a talk but, if they had, it would have been a nice surprise. I suppose I could try submitting an abstract to another conference but I think I would rather focus on (hopefully) publishing a paper.

Reflection: End of Week 9

Nothing interesting really happened this week. This week and next week are either presentations (poster/powerpoint) or preparing for presentations. Hence, I mainly polished the materials I had. Meaning, I made small tweaks to my poster; I worked on some new theorems to add into my paper at a later date; or I practiced my presentation, among other things. I am slightly nervous for the poster presentation because I've never done one before. I've written papers and I've given presentations but I've never done anything related to a poster. However, seeing my poster printed and how well it turned out calmed that anxiety. Lastly, I FINALLY completed those ethics training assignments. Overall, I'm hoping next week goes well!

Reflection: End of Week 10

I don't have much to say. All of my presentations went well. Yes, I wish I could have changed a few things but those changes could only happen if I had more than ten weeks to conduct research. Regarding my time at Marquette, I had a wonderful REU experience. I loved working with my mentor. I discovered a lot about graduate schools, writing mathematics papers, ethical research, and delineating between the development of mathematics and teaching/learning it. I would absolutely do this again.
