Polynomial functors and representations of wreath products
Friday 15th August, 12:05-12:55pm,
Carslaw 373.
Any reflection group has a graded representation on the cohomology
of the corresponding hyperplane complement - the character of this
representation has been calculated in most cases by Gus Lehrer.
I will discuss an alternative approach in the case where the group
is the wreath product of a symmetric group and a cyclic group.
This uses a generalization of the classical link between composition
of polynomial functors and plethysm.
