Equivalences between GIT quotients of Landau-Ginzburg B-models
Ed Segal
We define the category of B-branes in a (not necessarily affine) Landau-Ginzburg B-model, incorporating the notion of R-charge. Our definition is a direct generalization of the cat…

The closed state space of affine Landau-Ginzburg B-models
Ed Segal
We study the category of perfect cdg-modules over a curved algebra, and in particular the category of B-branes in an affine Landau-Ginzburg model. We construct an explicit chain ma…
