Revisiting the Quantum Geometry of Torus-fibered Calabi-Yau Threefolds
Boris Pioline, Thorsten Schimannek
About ten years ago, Katz, Klemm and Huang conjectured that topological string amplitudes on compact, elliptically fibered Calabi-Yau threefolds at fixed base degree could be expre…

The twisted geometry of 6d F-theory vacua with discrete gauge symmetries
David Jaramillo Duque, Amir-Kian Kashani-Poor, Thorsten Schimannek
We study the fate of discrete gauge groups and discrete charges of gravitational theories under twisted circle compactification. We then apply our results to six-dimensional F-theo…

In search of almost generic Calabi-Yau 3-folds
Thorsten Schimannek
We call a projective Calabi-Yau (CY) 3-fold almost generic if it has only isolated nodes as singularities and the homology classes of all of the exceptional curves in an analytic s…
