AbstractWe elaborate on construction of a derived Lagrangian intersection theory on moduli spaces of 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 normall crossing singular variety composed of Fano threefolds meeting along a K3. The deformation invariance arguments, to...
Abstract Moduli spaces of quadratic differentials on Riemann surfaces appear in quite different contexts such as the dynamics of polygonal billiards and spaces of stability conditions. This talk provides an introduction to the geometry of these moduli spaces and compares the state of the art with the knowledge on the classical moduli space of curves.About the Speaker Martin MöllerGoethe-Univers...
