Title: Equivariant quantum differential equation, Stokes bases, and K-theory for a projective space

Abstract:

I will consider the equivariant quantum differential equation for the projective space P^{n−1} and describe the Stokes bases of the differential equation at its irregular singular point in terms of the exceptional bases of the equivariant K-theory algebra of P^{n−1} and a suitable braid group action on the set of exceptional bases.
