Wilson't Hooft算子的代数

The algebra of Wilson-'t Hooft operators

Anton Kapustin, Natalia Saulina

摘要:

本文研究了规范群为G的扭曲N=4超杨-米尔斯理论中Wilson-'t Hooft算子的算子乘积展开. Montonen-Olive对偶对OPE有很强的约束,并且在G=SU(2)的情况下完全决定了它。从数学的角度来看,Montonen-Olive对偶预言了仿射格拉斯曼空间中Schubert胞腔上的某些等变向量丛的L^2 Dolbeault上同调。我们验证了其中的一些预测。我们还对拓扑场论中的高级范畴和缺陷作了一些一般性的观察。

英文摘要:

We study the Operator Product Expansion of Wilson-'t Hooft operators in a twisted N=4 super-Yang-Mills theory with gauge group G. The Montonen-Olive duality puts strong constraints on the OPE and in the case G=SU(2) completely determines it. From the mathematical point of view, the Montonen-Olive duality predicts the L^2 Dolbeault cohomology of certain equivariant vector bundles on Schubert cells in the affine Grassmannian. We verify some of these predictions. We also make some general observations about higher categories and defects in Topological Field Theories.
