Colored Vertex Models and Iwahori Whittaker Functions

Ben Brubaker, Valentin Buciumas, Daniel Bump +1

We give a recursive method for computing all values of a basis of Whittaker functions for unramified principal series invariant under an Iwahori or parahoric subgroup of a split re…

Colored five-vertex models and Demazure atoms

Ben Brubaker, Valentin Buciumas, Daniel Bump +1

Type A Demazure atoms are pieces of Schur functions, or sets of tableaux whose weights sum to such functions. Inspired by colored vertex models of Borodin and Wheeler, we will cons…
