A Mathematical Theory of Quantum Sheaf Cohomology
Ron Donagi, Josh Guffin, Sheldon Katz +1
The purpose of this paper is to present a mathematical theory of the half-twisted gauged linear sigma model and its correlation functions that agrees with and extends resul…
Physical aspects of quantum sheaf cohomology for deformations of tangent bundles of toric varieties
R. Donagi, J. Guffin, S. Katz +1
In this paper, we will outline computations of quantum sheaf cohomology for deformations of tangent bundles of toric varieties, for those deformations describable as deformations o…
Quantum Sheaf Cohomology, a précis
Josh Guffin
We present a brief introduction to quantum sheaf cohomology, a generalization of quantum cohomology based on the physics of the (0,2) nonlinear sigma model.
On the existence of affine Landau-Ginzburg phases in gauged linear sigma models
Patrick Clarke, Josh Guffin
We prove a simple criterion for the existence of an affine Landau-Ginzburg point in the Kähler moduli space of a gauged linear sigma model.
A-twisted heterotic Landau-Ginzburg models
Josh Guffin, Eric Sharpe
In this paper, we apply the methods developed in recent work for constructing A-twisted (2,2) Landau-Ginzburg models to analogous (0,2) models. In particular, we study (0,2) Landau…
A-twisted Landau-Ginzburg models
Josh Guffin, Eric Sharpe
In this paper we discuss correlation functions in certain A-twisted Landau-Ginzburg models. Although B-twisted Landau-Ginzburg models have been discussed extensively in the literat…
