Title : Genus 1 fibered Calabi-Yau 3-folds with 5-sections - A GLSM perspective
Elliptic and genus one fibered Calabi-Yau spaces play a prominent role in string theory and mathematics. In this talk we will discuss examples and properties of a class of Calabi-Yau threefolds with 5-sections. These Calabi-Yaus cannot be constructed by means of toric geometry. One way to obtain them is as vacuum manifolds of gauged linear sigma models (GLSMs) with non-abelian gauge groups. This approach makes it possible to find connections between different genus one fibrations with 5-sections that fit into the framework of homological projective duality. Furthermore we briefly discuss applications in topological string theory and M-/F-theory. This is joint work with Emanuel Scheidegger and Thorsten Schimannek.
