# Phases Of N=2 Theories In 1+1 Dimensions With Boundary

@article{Herbst2008PhasesON, title={Phases Of N=2 Theories In 1+1 Dimensions With Boundary}, author={Manfred Herbst and Kentaro Hori and David C. Page}, journal={arXiv: High Energy Physics - Theory}, year={2008} }

We study B-type D-branes in linear sigma models with Abelian gauge groups. The most important finding is the grade restriction rule. It classifies representations of the gauge group on the Chan-Paton factor, which can be used to define a family of D-branes over a region of the Kahler moduli space that connects special points of different character. As an application, we find a precise, transparent relation between D-branes in various geometric phases as well as free orbifold and Landau-Ginzburg…
