关于IIB型弦论的整体反常

On global anomalies in type IIB string theory

Hisham Sati

摘要:

研究了具有非平凡中上同调的IIB型弦论的整体引力反常。这就需要研究这个群上的超同态的作用。几个结果和建设,包括最近消失的结果,通过椭圆型,使人们有可能考虑这个问题。一路上,我们详细描述的交叉配对和行动的同胚,并突出各种结构的外观,包括Rochlin不变量及其变体的映射环面。

英文摘要:

We study global gravitational anomalies in type IIB string theory with nontrivial middle cohomology. This requires the study of the action of diffeomorphisms on this group. Several results and constructions, including some recent vanishing results via elliptic genera, make it possible to consider this problem. Along the way, we describe in detail the intersection pairing and the action of diffeomorphisms, and highlight the appearance of various structures, including the Rochlin invariant and its variants on the mapping torus.
