Eric Sommers (University of Massachusetts, Amherst) leads this Lie Groups Seminar, unpacking Lusztig's families of Weyl group representations through the lens of noncrossing partitions in type A. The talk highlights how this combinatorial viewpoint connects with Springer theory and Lusztig's parametrization of principal series unipotent representations for finite Chevalley groups.
