BPS穿墙与拓扑串

BPS Wall Crossing and Topological Strings

Sergio Cecotti, Cumrun Vafa

摘要:

通过在弦论中嵌入N=2的规范理论,并利用弦对偶性,我们将具有任意电荷和磁荷的BPS态的计数映射到由SW曲线数据构造的相关几何上的A模型拓扑弦的计算。我们展示了如何猜想Kontsevich和Soibelman关于墙穿越,以及一个更精致的版本,捕捉自旋内容的BPS状态,是一个自然的结果。在A-膜上实现的Chern-Simons理论和一个twistorial结构起了关键作用。

英文摘要:

By embedding N=2 gauge theories in string theory and utilizing string dualities we map the counting of BPS states with arbitrary electric and magnetic charges to computations of an A-model topological string on an associated geometry constructed from the data of the SW curve. We show how the conjecture of Kontsevich and Soibelman regarding wall crossing, as well as a more refined version which captures the spin content of BPS states, is a natural consequence. Chern-Simons theory realized on A-branes and a twistorial construction play key roles.
