A quantized Riemann-Hilbert problem in Donaldson-Thomas theory
Anna Barbieri, Tom Bridgeland, Jacopo Stoppa
We introduce Riemann-Hilbert problems determined by refined Donaldson-Thomas theory. They involve piecewise holomorphic maps from the complex plane to the group of automorphisms of…

A smooth compactification of spaces of stability conditions: the case of the -quiver
Anna Barbieri, Martin Möller, Jeonghoon So
We propose a notion of multi-scale stability conditions with the goal of providing a smooth compactification of the quotient of the space of projectivized Bridgeland stability cond…
