Felix Thimm (UBC Vancouver) - Wall-Crossing and the DT/PT3 Descendant Correspondence

Wall-crossing is used in enumerative geometry to compare various counting invariants via explicit formulas. It has emerged as a powerful tool for computations and in the study of properties of generating series of such enumerative invariants. I will present joint work with N. Kuhn and H. Liu on how to use localization of virtual classes to wall-cross invariants with descendant insertions in equivariantly Calabi-Yau 3-fold geometries.
