Supercharacter theories for algebra groups defined by involutions
The notion of supercharacter of an algebra group originated with the work of C. André and was then axiomatized by Diaconis and Isaacs. In his doctoral thesis, A. Neto established supercharacter theories for the orthogonal and the symplectic groups (subgroups of the unitriangular group with entries in a finite field). In this seminar we present a generalization of these theories for algebra groups defined by involutions.
