The Testerman Group

The Testerman Group, led by Donna Testerman, focuses on the subgroup structure of semisimple linear algebraic groups and finite simple groups of Lie type. Their research delves into the representation theory of these groups, properties of unipotent elements, and multiplicity-free representations. They have published extensively on topics such as cohomology in singular blocks, duality and bicrystals, and almost cyclic regular semisimple elements. The group actively organizes workshops and seminars, contributing significantly to the field of algebraic geometry and representation theory.
