Equivalued affine springer fibers in mixed characteristic
Jingren Chi
We study Witt-vector affine Springer fibers for tame equi-valued conjugacy classes in tamely ramified groups. Following the approach of Goresky-Kottwitz-MacPherson in the equal cha…
Witt vector affine Springer fibers
Jingren Chi
We establish dimension formulas for the Witt vector affine Springer fibers associated to a reductive group over a mixed characteristic local field, under the assumption that the gr…
Geometry of Kottwitz-Viehmann Varieties
Jingren Chi
We study basic geometric properties of Kottwitz-Viehmann varieties, which are certain generalizations of affine Springer fibers that encode orbital integrals of spherical Hecke fun…
The geometry of some generalized affine Springer fibers
Jingren Chi
We study basic geometric properties of some group analogue of affine Springer fibers and compare with the classical Lie algebra affine Springer fibers. The main purpose is to formu…
