Generalized Weyl modules and nonsymmetric q-Whittaker functions

Advances in Mathematics. 2018. Vol. 330. P. 997-1033.

We introduce generalized global Weyl modules and relate their graded characters to nonsymmetric Macdonald polynomials and nonsymmetric q-Whittaker functions. In particular, we show that the series part of the nonsymmetric q-Whittaker function is a generating function for the graded characters of generalized global Weyl modules.
