Stability conditions on the A2 quiver

Tom Bridgeland (University of Sheffield)

Wednesday 7th November, 2018 16:00-17:00 Maths 311B


I will talk about joint work with Yu Qiu and Tom Sutherland which is available on the arXiv. The aim is to describe the space of stability conditions on the various Calabi-Yau triangulated categories associated to the A2 quiver. The answer relates in an interesting way to the Frobenius manifold for the unfolding space of the  singularity x^3=0. I will not assume that you know what a stability condition is, but some familiarity with triangulated categories and t-structures will definitely be helpful!
