B-branes and the Derived Category

High Energy Physics - Theory 2017-08-23 v1

Abstract

By a direct CFT computation, the spectrum of the topological B-model is compared to Ext groups of sheaves. A match can only be made if abstract vector bundles on holomorphic submanifolds are twisted by the canonical Spinc\mathrm{Spin}^c structure of its support in describing physical branes.
