Title:Special geometry for invertible singularities and localization in GLSM
Abstract: Special geometry captures quantum cohomology or period integrals of Calabi-Yau threefolds. Invertible singularities describe a large class of Calabi-Yau hypersurfaces in weighted projective spaces generalizing the quintic threefold. I will explain how to perform computations of the special geometry, particularly period integrals and real structure, for the case of invertible singularities with arbitrary number of polynomial deformations (e.g. 101 for the quintic threefold). I will also tell how to build mirror symmetric GLSMs and show that their spherical partition functions match exactly the B-model expressions.
