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

We consider the equivariant quantum differential equation for projective space $$P^{n-1}$$ and introduce a compatible system of difference equations. prove an gamma theorem , which describes asymptotics at its regular singular point in terms characteristic class tangent bundle . describe Stokes bases irregular exceptional K-theory algebra suitable braid group action on set bases. Our results are version well-known Dubrovin Guzzetti..
