Shalika germs for tamely ramified elements in $G L_{n}$

Oscar Kivinen, Cheng-Chiang Tsai

We prove explicit combinatorial formulas for various germ expansions of orbital integrals of tamely ramified elements in $G L_{n} (F)$ , where $F$ is a nonarchimedean local field. The r…

On the affine Springer fibers inside the invariant center of the small quantum group

Nicolas Hemelsoet, Oscar Kivinen, Anna Lachowska

Let $u_{ζ}^{\lor}$ denote the small quantum group associated with a simple Lie algebra $g^{\lor}$ and a root of unity $ζ$ . In [9], a geometric realization of $Z(\ma…
