非几何通量的几何action

A geometric action for non-geometric fluxes

David Andriot, Olaf Hohm, Magdalena Larfors, Dieter Lust, Peter Patalong

摘要:

我们给出了非几何Q和R通量的几何解释。为此,我们考虑双场论的制定,是有关的传统的一个字段的重新定义采取的形式的T-对偶反演。R通量是一个张量下的同态,并满足一个非平凡的Bianchi恒等式。Q通量可以被看作是一个连接的一部分,该连接使绕线导数相对于非同态协变。我们给出了一个高维的行动与动力学项的R通量和一个'双'爱因斯坦-希尔伯特项包含连接Q。

英文摘要:

We give a geometrical interpretation of the non-geometric Q and R fluxes. To this end we consider double field theory in a formulation that is related to the conventional one by a field redefinition taking the form of a T-duality inversion. The R flux is a tensor under diffeomorphisms and satisfies a non-trivial Bianchi identity. The Q flux can be viewed as part of a connection that covariantizes the winding derivatives with respect to diffeomorphisms. We give a higher-dimensional action with a kinetic term for the R flux and a 'dual' Einstein-Hilbert term containing the connection Q.
