### Permutation modules for the symmetric group

Algebra and Geometry Seminar

30th May 2018, 2:30 pm – 3:30 pm

Howard House, 4th Floor Seminar Room

I will present a general method to determine the irreducible components (and their multiplicity) of a permutation module of the symmetric group over a field of characteristic zero, avoiding characters. Some examples will be discussed. The result is a joint work with A. A. Ivanov and M. Mainardis.
