通过在弦理论中嵌入N=2规范理论,并利用弦的对偶性,我们将具有任意电荷和磁荷的BPS态的计数映射到基于SW曲线数据构建的相关几何上的a模型拓扑弦的计算。我们展示了Kontsevich和Soibelman关于壁穿越的猜想,以及捕获BPS状态自旋内容的更精细的版本,是一个自然的结果。在a -膜上实现的chen - simons理论和扭转结构起着关键作用。
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.
