扭曲Poisson结构与非交换/非结合闭弦几何

Twisted Poisson Structures and Non-commutative/non-associative Closed String Geometry

Dieter Lust

摘要:

在本文中,我们讨论的非交换和非结合的几何,出现在非几何闭弦背景。T-对偶性和双场论在这类非几何弦背景下的有效作用量的计算中起着重要的作用。正如我们将要讨论的那样,闭合弦(对偶)坐标和(对偶)动量的非对易和非结合代数可以用扭曲泊松结构来数学描述,与在磁场中运动的点粒子的相空间密切类似。

英文摘要:

In this paper we discuss non-commutative and non-associative geometries that emerge in the context of non-geometric closed string backgrounds. T-duality and doubled field theory plays an important role in formulating the corresponding effective action for these kind of non-geometric string backgrounds. As we will argue, the emerging non-commutative and non-associative algebras for the closed string (dual) coordinates and (dual) momenta can be mathematically described by a twisted Poisson structure, in closed analogy to the phase space of a point particle moving in the field of a magnetic monopole.
