Exact indices for D-particles, flow trees and the derived category

High Energy Physics - Theory 2010-10-06 v1

Abstract

In arXiv:0909.0508 D-particle degeneracies were calculated using novel methods. By analysing this refined computation of the index in the setting of the topological B model, a correspondence is found between flow trees in the supergravity description and B-branes in the topological theory. This enables us to use the same refinement also for single flows. A concrete example will be given, providing strong support for this method, while at the same time confirming the prediction of a new elliptic genus in arXiv:0909.0508.
