广义几何在四维超引力中的应用

Generalized geometry applied to 4d-supergravity

Sara Oriana Tavares

摘要:

广义复几何是一个强有力的形式主义的例子,它试图构造一种适合于弦论的语言。由于统一辛和复流形作为更广泛结构的特殊情况的显着属性,它被证明是在试图描述T-对偶时使用的正确工具。关键思想是将两种几何都看作是正切和余切丛的直和运算,而不是通常的方法,只有正切空间是相关的。在这篇论文中,我们将有兴趣发展一个形式主义,从这些想法中汲取,但对于十一维M理论的玩具模型:Ovrut和Waldlett介绍的三形式超引力。

英文摘要:

Generalized complex geometry is an example of a powerful formalism to attempt the construction of a language adequate to string theory. With the remarkable property of unifying symplectic and complex manifolds as special cases of a broader structure it is proving to be the right tool to use when trying to describe T-duality. The key idea was to look at both geometries as operations in the direct sum of tangent and cotangent bundle as opposed to the usual approach, where only the tangent spaces are relevant. In this thesis we will be interested in developing a formalism drinking from these ideas but for a toy model of eleven dimensional M-theory: three-form supergravity as introduced by Ovrut and Waldram.
