ZMP Seminar - Summer Term 2021
About
- The topic of this term's ZMP seminar is Stability conditions.
- Abstract: Approximately 15 years ago Tom Bridgeland introduced the notion of stability condition on a triangulated category as a mathematical framework to understand Douglas' Pi-stability for D-branes in string theory. It turns out that the space Stab(D) of stability conditions on a fixed triangulated category D is a (possibly infinite-dimensional) complex manifold. If D is a triangulated three-dimensional Calabi-Yau category, then its Donaldson-Thomas invariants can be encoded into a geometric structure on Stab(D), called a Joyce structure, which in turn gives rise to a complex hyperkähler structure on the total space of the tangent bundle of Stab(D). In this seminar we would like to explore this circle of ideas starting from its physical origin in the work of Douglas.
