Unipotent elements and generalized exponential maps

Paul Sobaje

Let $G$ be a simple and simply connected algebraic group over an algebraically closed field $k$ of characteristic $p > 0$ . Assume that $p$ is good for the root system of $G$ and…

Varieties of $G_{r}$ -summands in Rational $G$ -modules

Paul Sobaje

Let $G$ be a simple simply connected algebraic group over an algebraically closed field $k$ of characteristic $p$ , with $r$ -th Frobenius kernel $G_{r}$ . Let $M$ be a $G_{r}$ -module and…

On exponentiation and infinitesimal one-parameter subgroups of reductive groups

Paul Sobaje

Let $G$ be a reductive algebraic group over an algebraically closed field $k$ of characteristic $p > 0$ , and assume $p$ is good for $G$ . Let $P$ be a parabolic subgroup with unipoten…
