Steinberg quotients and Smith-Treumann localization

Pramod N. Achar, Paul Sobaje

Smith-Treumann localization for sheaves on the affine Grassmannian of a reductive group has previously been studied by Leslie-Lonergan (for spherical sheaves) and by Riche-Williams…

On Donkin's Tilting Module Conjecture III: New Generic Lower Bounds

Christopher P. Bendel, Daniel K. Nakano, Cornelius Pillen +1

In this paper the authors consider four questions of primary interest for the representation theory of reductive algebraic groups: (i) Donkin's Tilting Module Conjecture, (ii) the…
