Affine Springer Fibers and the Affine Matrix Ball Construction for Rectangular Type Nilpotents

Pablo Boixeda Alvarez, Li Ying, Guangyi Yue

In this paper, we study the affine Springer fiber $\mathcal{F}{l}_N$ in type $A$ for rectangular type semisimple nil-element $N$ and calculate the relative position between irreduci…
