| Bridgeland stability and BPS states |
| Speaker: | Magnus Engenhorst (MPI Bonn) |
| Abstract: | Stability conditions play a prominent role in algebraic geometry and string theory. The initial motivation comes from Michael Douglas's work on D-branes. Bridgeland stability has now a lot of applications, e.g. in birational geometry or Teichmüller theory. In this short course we seehow one is naturally lead from the study of BPS states in supersymmetric field theories to stability conditions on certain (triangulated) categories associated with quivers with potential. We introduce the theory of (Bridgeland) stability conditions on triangulated categories and develop tools like tilting theory and t-structures. Further we discuss the relationship to Donaldson-Thomas invariants and (the categorification of) cluster algebras.
This short lecture course is aimed at advanced master students, PhD students and Postdocs in mathematics and physics. |

| Chiral anomalies and Transport |
| Speaker: | Karl Landsteiner (Universidad Autonoma de Madrid) |
| Abstract: | I will discuss how chiral anomalies give rise to dissipationless transport.
In particular I will try to relate well-known and old subjects, such
as the Quantum Hall Effect with new developments such as the
Chiral Magnetic Effect. I will emphasize the role of anomaly inflow and
interpret the Bardeen-Zumino terms relating covariant and consistent
currents in a way analogous to the Callen-Harvey mechanism. In analogy
to what in is called the "Bulk-Boundary" correspondence in the theory of the
QHE I will argue for a "Bulk-Bulk" correspondence in the theory of CME
related effects.
