# George H. Seelinger

I am a Mathematics PhD student at the University of Virginia studying algebraic combinatorics while keeping open arms towards representation theory and algebraic geometry; I am currently working under Dr. Jennifer Morse. Previously, I worked as a Data Scientist on real time bidding problems for an internet advertising company. Generally, I am interested in working on unsolved problems and enabling other problem solvers to be more effective.

Think we have met before? Here is my professional past and present travel schedule.

## Research and Writings • (Papers)

Also, as a resource for my cohort of graduate students, but also for other learning graduate students, I worked with various collaborators on creating class notes for first and some second year PhD program courses. You can see them here: First year course notes.

I also publicly post monographs I write for myself to clarify concepts and fill in details of books I read. You can see them here: Monographs; I also have made select notes for more advanced classes I have taken, but they are more likely to have errors and some are incomplete: Advanced course notes.

## Teaching • (All)

In Fall 2019, I teach Math 1310: Calculus I.

## Engagement, Outreach, and Service

I am a member of and webmaster for the UVA Association for Women in Mathematics (AWM). AWM works to encourage girls and women to study and have activer careers in the mathematical sciences and promote equal opportunity and equal treatment of girls and women in the mathematical sciences.

I volunteer as a UVA Math Ambassador to do math outreach in Charlottesville area grade schools.

I sometimes make contributions to the open source mathematical software SageMath, the most notable of which was overhauling the diagram algebras package with my collaborators as a result of my work on Brauer algebras. You can see all the tickets I have contributed to the SageMath trac server. If you are interested in contributing code to Sage, check out my development checklist and feel free to contact me if you have questions!

Previously, I have been a mentor for the UVA Math Department Directed Reading Program (DRP). The DRP pairs undergraduates interested in learning math outside the standard curriculum with graduate student mentors who guide them in reading some interesting and different mathematics.

## What's New

24 Jun 2019 » Garsiafest Lightning Talk: Raising Operators in Schubert Calculus • (PDF)

This past week I had the opportunity to give my first public research presentation as a graduate student at Adriano Garsia’s 90th birthday conference, Garsiafest, in San Diego at the Scripps Seaside Forum. My presentation mainly expanded on the information from my MAAGC Poster, but now one of the main conjectures is a theorem! You can look at the slides here. Eventually, they will also post a video of my talk on the conference website. It was truly an honor to present my work to so many people in my area and I look forward to presenting more work in the future.

This last weekend, I had an opportunity to attend and present a poster at the 2019 Mid-Atlantic Algebra, Geometry, and Combinatorics (MAAGC) conference in Philadelphia. The poster is about one of the projects I am currently working on to describe “$$K$$-theoretic $$k$$-Schur functions” with a raising operator formula which is a specialization of what we are currently calling “$$K$$-theoretic Catalan functions” since they generalize the description of Catalan functions that Blasiak, Morse, Pun, and Summers used to prove the Schur positivity of $$k$$-Schur functions.
