On conjugacy of unipotent elements in finite groups of Lie type
Simon M. Goodwin, Gerhard Roehrle
Let $\bfG$ be a connected reductive algebraic group defined over $\F_q$, where is a power of a prime that is good for $\bfG$. Let be the Frobenius morphism associated w…
Complete Reducibility and Separability
Michael Bate, Benjamin Martin, Gerhard Roehrle +1
Let G be a reductive linear algebraic group over an algebraically closed field of characteristic p > 0. A subgroup of G is said to be separable in G if its global and infinitesimal…
Spherical Nilpotent Orbits in Positive Characteristic
Russell Fowler, Gerhard Roehrle
Let G be a connected reductive linear algebraic group defined over an algebraically closed field of characteristic p. Assume that p is good for G. In this note we classify all the…
Special involutions and bulky parabolic subgroups in finite Coxeter groups
Goetz Pfeiffer, Gerhard Roehrle
The conjugacy classes of so-called special involutions parameterize the constituents of the action of a finite Coxeter group on the cohomology of the complement of its complexified…
