A gallery model for affine flag varieties

Abstract: Galleries, which are special sequences of elements in a Coxeter group, provide a nice combinatorial way of studying flag varieties. In this talk, we will discuss what these objects are, how they relate to each other, and how this relationship gives us a convenient recursion for computing certain double coset intersections in affine flag varieties. This talk is based on joint work with Elizabeth Milicģevicģ, Petra Schwer and Anne Thomas.
