Jasper Ty's math webpage

Welcome

I am a second-year Ph.D student at Drexel University. My advisor is Jonah Blasiak.

You can reach me at jlt383 ( something goes here ) drexel ( something goes here ) edu. My personal (non-math) website is at jasperty.net.

CV.

Interests

• Algebraic combinatorics
  • "type A" combinatorics; Young tableaux, crystals, ...
  • Noncommutative algebra
• Matrix and operator theory
  • TBD!

Preprints and publications

• ¯\_(ツ)_/¯

Math

Here's a small collection of things I've written, so far. Some links are broken due to laziness.

Notes

Notes I'm writing for classes I'm taking or topics I'm learning.

• Incomplete notes on Lie algebras
• Incomplete notes on symmetric functions

One-shots

• A neat sum identity
• exp is the inverse of log
• The Fundamental Theorem of Calculus

Other

• Notes on Hillar-Nie 2006, "An elementary and constructive solution to Hilbert's 17th Problem for matrices"

  Written for the Winter 2024 class "Positive Polynomials and Sums of Squares".
