G2流形的模空间

Moduli spaces of G2 manifolds

Sergey Grigorian

摘要:

本文综述了G2流形的模空间研究的最新进展。G2流形是具有特殊和乐群G2的7维流形。虽然它们是奇维的,但在许多方面,它们可以被认为是7维的卡-丘流形的类似物。它们在物理学中作为M-理论紧化的超对称真空解的自然候选者起着重要的作用。尽管物理动机,许多结果是纯粹的数学兴趣。在这里,我们涵盖了G2流形的基础知识,G2结构的局部变形理论和G2结构的模空间的局部几何。

英文摘要:

This paper is a review of current developments in the study of moduli spaces of G2 manifolds. G2 manifolds are 7-dimensional manifolds with the exceptional holonomy group G2. Although they are odd-dimensional, in many ways they can be considered as an analogue of Calabi-Yau manifolds in 7 dimensions. They play an important role in physics as natural candidates for supersymmetric vacuum solutions of M-theory compactifications. Despite the physical motivation, many of the results are of purely mathematical interest. Here we cover the basics of G2 manifolds, local deformation theory of G2 structures and the local geometry of the moduli spaces of G2 structures.
