Integral Polynomial Rings

January 01, 2020

Automorphisms of integral polynomial rings is an incredibly complicated group. This research asks which of those automorphisms fix a given polynomial.

This project started at Butler University's math research camp in 2019. I worked with Dr. Amber Russell to study a question posed in "The Kourovka Notebook." It asked to construct an algorithm that when given any function in an integral polynomial ring (of any number of variables) to find the automorphisms that fix that function.

The question asks about polynomial rings over the integers of any number of variables. One variable is trivial, two variables is difficult, and three variables is mostly uncharted territory. We stuck with two variables.

In January 2020 I traveled to Denver to present our poster at the joint mathematics meeting.
