Vanishing theorems for Shimura varieties at unipotent level [PDF]
, 2019 We show that the compactly supported cohomology of Shimura varieties of Hodge type of infinite $\Gamma_1(p^\infty)$-level (defined with respect to a Borel subgroup) vanishes above the middle degree, under the assumption that the group of the Shimura ...

The geometry of generalized Steinberg varieties
, 2004 For a reductive, algebraic group, G, the Steinberg variety of G is the set of all triples consisting of a unipotent element, u, in G and two Borel subgroups of G that contain u. We define generalized Steinberg varieties that depend on four parameters and

The structure of the pro-l-unipotent fundamental group of a smooth variety
, 2004 By developing a theory of deformations over nilpotent Lie algebras, based on Schlessinger's deformation theory over Artinian rings, this paper investigates the pro-l-unipotent fundamental group of a variety X. If X is smooth and proper, defined over a finite field, then the Weil conjectures imply that this group is quadratically presented.

, 2020 An affine varieties with an action of a semisimple group $G$ is called "small" if every non-trivial $G$-orbit in $X$ is isomorphic to the orbit of a highest weight vector. Such a variety $X$ carries a canonical action of the multiplicative group $\mathbb{

Closure of Steinberg Fibers and Affine Deligne-Lusztig Varieties
, 2010 We discuss some connections between the closure (F) over bar of a Steinberg fiber in the wonderful compactification of an adjoint group and the affine Deligne-Lusztig varieties X(w)(1) in the affine flag variety.
