Title:  Singular affine structures, real Monge-Ampère equations and unit simplices

Abstract:   Recent developments in complex geometry have highlighted the importance of real Monge-Ampere equations on singular affine manifolds, in particular for the SYZ conjecture concerning collapsing families of Calabi-Yau manifolds. We show that for symmetric data, the real Monge-Ampere equation on the unit simplex admits a unique Aleksandrov solution. This is concluded as a special case of a result giving necessary and sufficient conditions in terms of optimal transport for existence of solutions. I will outline the proof and explain a built in phenomena reminiscent of free boundary problems. Time permitting, I will discuss an application to the SYZ conjecture related to recent work by Y. Li.
