Speaker: Greg Stevenson (AU) Abstract: Differential graded algebras, which consist of a graded algebra together with a square-zero derivation, are an algebraic way of modelling multiplication up to homotopy. They are well adapted to, and arise naturally from, the study of derived categories in algebraic geometry. In general, the presence of the derivation makes these very complicated objects which are not necessarily amenable to usual techniques from ring theory. In my talk I'll explain some recent results, by my student Isambard Goodbody and others, in the setting where the underlying algebra is finite dimensional over some field. In this case, a surprising number of results from the theory of finite dimensional algebras can be generalized to the differential graded setting.

Speaker: Hannah Dell (University of Edinburgh) Abstract: The space of Bridgeland stability conditions on a given triangulated category is a complex manifold, which gives us a way to extract geometry from homological algebra. An explicit description is only known in a few cases. In this talk, I will discuss two approaches to studying stability conditions on derived categories of surfaces that are free quotients by finite abelian groups. One method is via Le Potier functions, which characterise the existence of slope-semistable sheaves. The second method uses Deligne’s notion of group actions on triangulated categories to describe a connected component of so-called geometric stability conditions inside the stability manifold of these free abelian quotients when the cover has finite Albanese morphism. A consequence of this is a disproof of the expectation that surfaces with irregularity 0 always admit a wall of the geometric chamber. This is based on arXiv:2307.00815.
