加倍、T-对偶与广义几何:一个简单模型

Doubling, T-Duality and Generalized Geometry: a Simple Model

Vincenzo Emilio Marotta, Franco Pezzella, Patrizia Vitale

摘要:

本文将一个简单的力学系统--三维各向同性刚性转子系统作为0+1场论来研究,旨在进一步研究广义/二重几何与二重世界表形式主义/二重场论之间的关系。该模型被定义在SU(2)的群流形上,并以SU(2)的Poisson-Lie对偶作为位形空间,引入了一个对偶模型。然后定义了一个具有位形空间SL(2,C)的广义作用,即SU(2)群的Drinfel'd对偶:一旦约束被实现,它就退化为旋转子的原始作用或其对偶。新操作包含的变量是原始操作的两倍。此外,它的几何结构可以用广义几何来理解。关键词:广义几何,双场论,T-对偶,Poisson-Lie对称。

英文摘要:

A simple mechanical system, the three-dimensional isotropic rigid rotator, is here investigated as a 0+1 field theory, aiming at further investigating the relation between Generalized/Double Geometry on the one hand and Doubled World-Sheet Formalism/Double Field Theory, on the other hand. The model is defined over the group manifold of SU(2) and a dual model is introduced having the Poisson-Lie dual of SU(2) as configuration space. A generalized action with configuration space SL(2,C), i.e. the Drinfel'd double of the group SU(2), is then defined: it reduces to the original action of the rotator or to its dual, once constraints are implemented. The new action contains twice as many variables as the original. Moreover, its geometric structures can be understood in terms of Generalized Geometry. keywords: Generalized Geometry, Double Field Theory, T-Duality, Poisson-Lie symmetry.
