Conference: Representations of Symmetric Groups, Hecke Algebras and KLR Algebras

Introduced by J.A. Green in 1959, vertices of indecomposable modules over modular group algebras have proved to be important invariants linking the global and local representation theory of finite groups over fields of positive characteristic. In this talk I will describe the problem of determining vertices for simple modules of the symmetric groups. In particular I will present the recently completed classification of the vertices of simple modules labelled by hook partitions. This is joint work with Susanne Danz.
