Title: D-brane central charge and Landau-Ginzburg orbifolds II
Abstract:Last time we learned about the D-brane central charge in mathematics and physics, and we suggested to view it as a function on the stringy Kaehler moduli space of a variation of GIT quotients and their associated triangulated categories. This situation has a nice description in physics in terms of the gauged linear sigma model whose phases correspond to various regions of the Kaehler moduli space. This time we focus on the gauged linear sigma model and on the Landau-Ginzburg orbifold phase to compare the resulting D-brane central charge functions.
