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 $…
