Ομιλιτής: Stephen Donkin (University of York, UK) Title:Greene's Theorem and ideal of the group algebra of a symmetric group

Abstract:

We show that certain factor rings of the group algebra of a symmetric group have natural bases of group elements. These include the factor rings studied by Raghavan, Samuel and Subrahmanyam and by Doty.
We also give generators for the annihilator of certain permutation modules for symmetric groups.
