Chayim Lowen

Welcome to my personal webpage.

I am a fourth-year graduate student at Princeton University. I received my Bachelor's degree from the University of Toronto in 2023. My advisor is June Huh.

I am interested broadly in algebraic combinatorics and in the interplay between the algebraic, geometric and combinatorial aspects of matroid theory.

Here is my Curriculum Vitae.

I may be contacted at chayiml [at] princeton [dot] edu.

Blowups of a Gm-surface at a fixed point. — Blowups of a $\mathbb{G}_m$-surface at a fixed point.

Preprints

Koszul Orlik–Solomon algebras from non-supersolvable arrangements (with Tuong Le and Jason McCullough).
Matroid flat counts can have many peaks (with Alexander Divoux, Matt Larson, and Shouda Wang).
Structural properties of Białynicki-Birula decompositions (with Teddy Gonzales).
On the asymptotic behavior of finite hyperfields (with Tuong Le).
Simultaneous generating sets for flags (with Federico Glaudo and Noah Kravitz).
