(异质)双场论和例外场论是明显的对偶协变表述,描述了各种超弦和m理论紧化的低能极限。这些场论可以通过引入适当的参数化广义度量和应用适当选择的截面条件而简化为标准描述。在本文中,我们将这些公式应用于非几何背景。在与非几何通量相关的对偶场中,我们引入了广义度规的不同参数化。在一定的简化假设下,我们构造了新的非几何背景的有效动作。然后,我们研究了由外来膜来源的非几何背景,并找到了它们的U -对偶单矩阵。由这些单矩阵得到的奇异膜的电荷与由非几何通量积分得到的电荷一致。
A bstractThe (heterotic) double field theories and the exceptional field theories are manifestly duality covariant formulations, describing low-energy limit of various super-string and M-theory compactifications. These field theories are known to be reduced to the standard descriptions by introducing appropriately parameterized generalized metric and by applying suitably chosen section conditions. In this paper, we apply these formulations to non-geometric backgrounds. We introduce different parameterizations for the generalized metric in terms of the dual fields which are pertinent to non-geometric fluxes. Under certain simplifying assumptions, we construct new effective action for non-geometric backgrounds. We then study the non-geometric backgrounds sourced by exotic branes and find their U -duality monodromy matrices. The charge of exotic branes obtained from these monodromy matrices agrees with the charge obtained from the non-geometric flux integral.
