Title: On self-extensions of irreducible modules for symmetric groups

Abstract: We work in the context of the modular representation theory of the symmetric groups. A long-standing conjecture, from the late 80s, suggests that there are no (non-trivial) self-extensions of irreducible modules over fields of odd characteristic. In this talk we will highlight several new positive results on this conjecture. This is a joint work with S. Kleshchev and L. Morotti.
