Upcoming Seminars:

26-06-2018, 1:45pm at the TU: Thorsten Schimannek (Univ.  Bonn) will talk on `Fourfolds, integral Fluxes and Modularity'

Abstract: Four-dimensional N=1 vacua of F-theory are determined by three discrete choices.  A topological type of elliptically fibered Calabi-Yau fourfolds, a choice of flux and a minimum of the corresponding scalar potential. While there are several constructions that together provide an abundance of elliptic Calabi-Yaus, the choice of properly quantized flux is in general more involved. The talk will start with a brief review of F-theory and the geometry of Calabi-Yau fourfolds.  I will then explain how topological string theory and homological mirror symmetry can be used to determine properly quantized choices for a particular class of fluxes.  Additional comments will be about certain Fourier-Mukai transformations that act on the underlying basis of topological branes and lead to modular properties of the Gromov-Witten potentials on non-singular Calabi-Yau fourfolds.
