Bigrassmannian permutations and Verma modules

Volodymyr Mazorchuk

Uppsala University

In this talk I will try to describe an unexpected connection between bigrassmannian permutations and the cokernel of inclusions between Verma modules (over the special linear Lie algebra). An application (and the original motivation) is a complete description of the first extension space from a simple highest wegiht module to a Verma modules. This is a report on a joint work with Hankyung Ko and Rafael Mrden.
