Abstract
Killing forms are bilinear forms most well-known in the context of Lie algebras. Applying them to certain Lie algebras based on finite groups yields an expression in terms of centralizers in the group. In this talk, based on a collaboration with Kevin Piterman, we cover some problems concerning the non-degeneracy of these forms and study the case of the finite simple groups PSL(2,q).
