Linus Setiabrata


Hi! I am a grad student at UChicago, working with Victor Ginzburg. Previously, I was an undergrad at Cornell.

My email is linus at math dot uchicago dot edu.

I care about many things, including algebraic combinatorics and representation theory. Most recently I've been thinking about hypertoric varieties. I also particularly like flag/quiver varieties, generalized permutahedra and related polytopes, and cluster algebras.

Here is a list of publications. Here's my CV.

Here are slides for a talk on Heronian friezes.

If I were a Springer-Verlag Graduate Text in Mathematics, I would be Lawrence C. Washington's Introduction to Cyclotomic Fields.

I am a carefully written exposition of a central area of number theory that can be used as a second course in algebraic number theory. Starting at an elementary level, I cover p-adic L-functions, class numbers, cyclotomic units, Fermat's Last Theorem, and Iwasawa's theory of Zp-extensions, leading the reader to an understanding of modern research literature. Many exercises are included.
