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…
Enumerative geometry and modularity in two-modulus K3-fibered Calabi-Yau threefolds
Charles Doran, Boris Pioline, Thorsten Schimannek
Motivated in part by the modular properties of enumerative invariants of K3-fibered Calabi-Yau threefolds, we introduce a family of 39 Calabi-Yau mirror pairs with $h_{1,1}…
New non-commutative resolutions of determinantal Calabi-Yau threefolds from hybrid GLSM
Sheldon Katz, Thorsten Schimannek
We study topological strings on non-commutative resolutions of singular Calabi-Yau threefolds that are double covers of , ramified over determinantal octic surfaces.…
Quantum geometry, stability and modularity
Sergei Alexandrov, Soheyla Feyzbakhsh, Albrecht Klemm +2
By exploiting new mathematical relations between Pandharipande-Thomas (PT) invariants, closely related to Gopakumar-Vafa (GV) invariants, and rank 0 Donaldson-Thomas (DT) invariant…
