Recursive algorithm and log-concavity of representations on the cohomology of $M_{0, n}$

Jinwon Choi, Young-Hoon Kiem, Donggun Lee

We provide a programmable recursive algorithm for the $S_{n}$ -representations on the cohomology of the moduli spaces $M_{0, n}$ of $n$ -pointed stable curv…

Automorphisms and deformations of regular semisimple Hessenberg varieties

Patrick Brosnan, Laura Escobar, Jaehyun Hong +4

We show that regular semisimple Hessenberg varieties can have moduli. To be precise, suppose $X$ is a regular semisimple Hessenberg variety of codimension $1$ in the flag variety $…
