SUMMARY:Geodesics and minimal surfaces
DESCRIPTION:Abstract: There are several properties of closed geodesics which are proven using its Hamiltonian formulation\, which has no analogue for minimal surfaces. I will talk about some recent progress in proving some of these properties for minimal surfaces.

SUMMARY:Donaldson-Thomas invariants and hyperkahler manifolds: the example of theories of class S[A1]
DESCRIPTION:Abstract: I will report on a project which aims to encode the DT invariants of a CY3 triangulated category in a geometric structure on its stability space. I will focus on a class of categories whose stability spaces were studied in previous joint work with Ivan Smith\, and which correspond in physics to theories of class S[A1]. I will describe the resulting geometric structures using a kind of complexified Hitchin system parameterising bundles on curves equipped with pencils of flat connections.
