关于E11运动方程的不同表述

On the different formulations of the E11 equations of motion

Peter West

摘要:

E ~(11)与其矢量表示的半直积的非线性实现,导出了引力子场、三形式场、六形式场、对偶引力子场和四水平场的运动方程,这些方程正确地描述了线性化水平上的十一维超引力自由度。含有一个导数的方程一般都是等价关系,而且往往是对偶关系。从这些方程中,通过求导,可以导出我们所熟悉的运动方程。整个方程层次是E11不变的,并且构造不需要E11以外的任何步骤。我们回顾了这些过去的发展,重点是在hep-th:1703.01305中被忽视的特征,我们也评论了其替代方法。

英文摘要:

The non-linear realisation of the semi-direct product of E11 with its vector representation leads to equation of motions for the fields graviton, three form, six form, dual graviton and the level four fields which correctly describe the degree of freedom of eleven dimensional supergravity at the linearised level. The equations with one derivative generically hold as equivalence relations and are often duality relations. From these equations, by taking derivatives, one can derive equations that are equations of motion of the familiar kind. The entire hierarchy of equations is E11 invariant and the construction does not require any steps beyond E11. We review these past developments with an emphasis on the features that have been overlooked in hep-th:1703.01305, whose alternative approach we also comment on.
