D-粒子、流树和导出范畴的精确指标
Exact indices for D-particles, flow trees and the derived category
摘要：
在arXiv：0909.0508中，使用新方法计算D-粒子简并度。通过分析拓扑B模型中的这种精细的指数计算，发现超引力描述中的流树与拓扑理论中的B-膜之间存在着对应关系。这使我们能够对单个流使用相同的细化。将给出一个具体的例子，为该方法提供强有力的支持，同时证实了arXiv：0909.0508中一个新的椭圆亏格的预测。
英文摘要：
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.
