Abstract:

The affine Coxeter group of type A has an explicit combinatorial interpretation as a group of infinite permutations. In this talk, I will introduce these permutations and discuss various combinatorial properties, such as the group's Poincaré series and a generalized notion of inversion. This talk is based on a paper by Björner and Brenti.
