Title:  Affine permutations of type A

Abstract:  In this talk, we will present results by Björner and Brenti on certain affine permutations. We show that the group of affine permutations realizes the affine Coxeter group of type A. We then consider some combinatorial properties of affine permutations. We exhibit bijections between affine inversion tables, defined analogously to the usual inversion tables of permutations, and certain integer partitions. Finally, we examine several partial orders on affine permutations.
