A computational approach to the Frobenius-Schur indicators of finite exceptional groups

Stephen Trefethen, C. Ryan Vinroot

We prove that the finite exceptional groups , , and have no irreducible complex characters with Frobenius-Schur indicator , and we list e…

Klyachko models of p-adic special linear groups

Joshua M. Lansky, C. Ryan Vinroot

We study Klyachko models of , where is a nonarchimedean local field. In particular, using results of Klyachko models for due to Heumos, Rallis,…

Extending real-valued characters of finite general linear and unitary groups on elements related to regular unipotents

Rod Gow, C. Ryan Vinroot

When n is odd, consider the finite general linear and unitary groups of rank n, extended by the inverse transpose automorphism. There are elements in the extended groups which squa…

On the characteristic map of finite unitary groups

Nathaniel Thiem, C. Ryan Vinroot

In his classic book on symmetric functions, Macdonald describes a remarkable result by Green relating the character theory of the finite general linear group to transition matrices…
