GLSMs for non-polynomial deformations and generalized complete intersection Calabi-Yau manifolds
Lara B. Anderson, James Gray, Eric Sharpe +1
Gauged Linear Sigma Models (GLSMs) have long been a key tool in understanding Calabi-Yau compactifications of string theory. While descriptions of complete intersections of polynom…
Three-dimensional orbifolds by 2-groups
Alonso Perez-Lona, Eric Sharpe
In this paper we generalize previous work on decomposition in three-dimensional orbifolds by 2-groups realized as analogues of central extensions, to orbifolds by more general 2-gr…
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…
Decomposition, Trivially-Acting Symmetries, and Topological Operators
Daniel Robbins, Eric Sharpe, Thomas Vandermeulen
Trivially-acting symmetries in two-dimensional conformal field theory include twist fields of dimension zero which are local topological operators. We investigate the consequences…
Decomposition, condensation defects, and fusion
Ling Lin, Daniel G. Robbins, Eric Sharpe
In this paper we outline the application of decomposition to condensation defects and their fusion rules. Briefly, a condensation defect is obtained by gauging a higher-form symmet…
Quantum K theory of Grassmannians, Wilson line operators, and Schur bundles
Wei Gu, Leonardo C. Mihalcea, Eric Sharpe +1
We prove a `Whitney' presentation, and a `Coulomb branch' presentation, for the torus equivariant quantum K theory of the Grassmann manifold , inspired from physi…
