我们研究了 Aganagic 和 Vafa 提出的一类新型几何过渡的物理和数学结构。这些转变的独特之处在于存在对陈-西蒙斯理论的开弦瞬子修正。我们应用 Witten 不久前提出的一个美丽想法,找到了开弦拓扑振幅和闭弦拓扑振幅之间的精确匹配。由于枚举技术和 Chern-Simons 计算的迷人相互作用,从开弦角度再现了闭弦振幅。
We investigate the physical and mathematical structure of a new class of geometric transitions proposed by Aganagic and Vafa. The distinctive aspect of these transitions is the presence of open string instanton corrections to Chern-Simons theory. We find a precise match between open and closed string topological amplitudes applying a beautiful idea proposed by Witten some time ago. The closed string amplitudes are reproduced from an open string perspective as a result of a fascinating interplay of enumerative techniques and Chern-Simons computations.
