The representation theory of symmetric groups starts with
the permutation modules. It turns out that the annihilator of a
permutation module can be described explicitly in terms of the
combinatorics of Murphy's cellular basis of the group algebra of the
symmetric group in question. In fact, we will show that the
annihilator is always a cell ideal. This is recent joint work with K.
Nyman.
