Spaces of Bridgeland stability conditions in representation theory
Anna Barbieri
The space of Bridgeland stability conditions is a complex manifold that can be attached to a triangulated category, of which it encodes some homological properties. These notes are…

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…

A Riemann-Hilbert problem for uncoupled BPS structures
Anna Barbieri
We study the Riemann-Hilbert problem attached to an uncoupled BPS structure proposed by Bridgeland in "Riemann-Hilbert problems from Donaldson-Thomas theory". We show that it has "…
