Abstract

I will discuss a class of Riemann-Hilbert problems which arise naturally from the wall-crossing formula in Donaldson-Thomas theory. As well as giving an explicit description of the simplest example, I will try to explain the motivating analogy with the deformed flat connection in the theory of Frobenius manifolds.
