Abstract
Studying wall crossing for Bridgeland stability conditions has led recently to many new results in the birational geometry of moduli spaces associated to smooth projective complex surfaces. The key tool is the introduction by Bayer and Macrì of a family of nef divisors on each moduli space of Bridgeland stable objects. I'll describe joint work with Bayer and Zhang that generalises this construction by removing the assumptions about smoothness and projectivity. I'll also explain why we care.
