Refined BPS numbers on compact Calabi-Yau threefolds from Wilson loops
Min-xin Huang, Sheldon Katz, Albrecht Klemm +1
We relate the counting of refined BPS numbers on compact elliptically fibred Calabi-Yau threefolds to Wilson loop expectations values in the gauge theories that emerge in vario…
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.…
Topological Strings on Non-Commutative Resolutions
Sheldon Katz, Albrecht Klemm, Thorsten Schimannek +1
In this paper we propose a definition of torsion refined Gopakumar-Vafa (GV) invariants for Calabi-Yau threefolds with terminal nodal singularities that do not admit Kähler crepant…
Local Gromov-Witten invariants of some simple normal crossing surfaces
Sheldon Katz, Sungwoo Nam
Inspired by M-theory and superconformal field theory, we extend the notions of local Gromov-Witten invariants from the case of del Pezzo surfaces to shrinkable surfaces, a class of…
Dimensional Reduction of B-Fields in F-theory
Sheldon Katz, Washington Taylor
We describe the dimensional reduction of the IIB B-fields in F-theory using a conjectured description of normalizable B-fields in terms of perverse sheaves. Computations are facili…
Enumerative geometry of the mirror quintic
Sheldon Katz, David R. Morrison
We evaluate the enumerative invariants of low degree on the mirror quintic threefold.
