SIMIS Seminar on Derived and Noncommutative Geometry: Shifted symplectic structures on derived Quot Schemes, Degenerations and Categorification of DT invariants
Speaker: Artan Sheshmani (BIMSA) Abstract: We discuss construction of a derived Lagrangian intersection theory of closely related moduli spaces of perfect complexes, with support on divisors on compact Calabi Yau threefolds. Our goal is to compute deformation invariants associated to a fixed linear system of divisors in CY3. We degenerate the CY3 into a normal-crossing …
