# Eric Stubley

Hello! I am a sixth year graduate student in the University of Chicago's Department of Mathematics. My advisor is Frank Calegari. I work in algebraic number theory, with a focus on Galois representations and Galois cohomology.

I use he and its derivative pronouns.

Perhaps you are looking for my CV?

## Research

### Papers

#### Class groups of Kummer extensions via cup products in Galois cohomology

[pdf][arXiv][journal] Joint work with Karl Schaefer. Transactions of the American Mathematical Society (2019). My advisor wrote a blog post about our work. We wrote some sage programs to gather large amounts of data on the class groups and p-th power congruences we study, which you can find on this github page.

I've been very fortunate to spend the past few summers teaching at Canada/USA Mathcamp. Mathcamp is a 5-week residential summer camp in mathematics for high school students from across the world. See below for a list of Mathcamp classes I've taught. If you're interested in seeing notes or homeworks from any of these classes please email me!

Summer 2020, at our Virtual Mathcampus:

• Introduction to ring theory (5 days)
• Grammatical group generation (2 days)
• Congruences of Bernoulli numbers and zeta values (4 days)
• Solving equations with origami (5 days)
• The lemma at the heart of my thesis (1 day)
• How to ask questions? (1 day)

Summer 2019, at Lewis & Clark College in Portland, Oregon:

• The centuries-old English tradition of publicly performing Hamiltonian cycles in Cayley graphs of symmetric groups (change ringing) (5 days, with Tim Black)
• Analysis with primes (5 days)
• Everything you ever wanted to know about finite fields (5 days)
• The sound of proof (1 day)
• Reciprocity laws in algebraic number theory (5 days)
• Infinitely many proofs of infinitely many primes (1 day)
