Invariants of Specht modules
If you have a question about this talk, please contact David Craven.
This talk is based on a joint work with S. Donkin. In a research paper of D. Hemmer the author conjectures that the module of fixed points for the symmetric group Sym(m) of a Specht module for Sym(n) (with n>m), over an algebraically closed filed of positive characteristic p, has a Specht series when viewed as a Sym(n−m)-module. In this talk we will provide a counterexample for each prime p.
