On Donkin's Tilting Module Conjecture IV: New Frontiers

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

Let be a simple, simply connected algebraic group scheme defined over , and let be the th Frobenius kernel. Donkin's famous Tilting Module Conjecture…

Linear Bounds for Cohomology of Algebraic Groups

Christopher P. Bendel, Nham Ngo

In this note, we establish an explicit upper bound for the dimension of the rational cohomology for a simple algebraic group over an algebraically closed field of prime characteris…

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…

Cohomology of algebraic groups, Lie algebras, and finite groups of Lie type

Christopher P. Bendel

Let G be a reductive algebraic group over a field of prime characteristic. One can associate to G (or subgroups thereof) its Lie algebra, its Frobenius kernels, and the finite Chev…
