E(7(7))和d=11超引力

E(7(7)) and d=11 supergravity

Christian Hillmann

摘要:

本论文首先研究了在不引入额外玻色子场的情况下,D=11的超引力是否可以提升到更高维的理论,通过将N=8 d=4的E(7(7))对称性解释为作用在60维限制或例外几何中的坐标对称性的一部分。证明了截断到d=7的D=11超引力的超对称性变化可以按预期的方式从这种特殊几何中再现出来。其次,详细回顾了Borisov和Ogievetsky从仿射线性子群与共形线性子群的联合非线性实现中构造具有仿射协方差的理论的过程,并通过讨论挠来推广这一过程。

英文摘要:

This thesis firstly investigates whether D=11 supergravity can be lifted to a higher dimensional theory without introducing additional bosonic fields by interpreting the E(7(7))-symmetry of N=8 d=4 supergravity as part of a coordinate symmetry acting in a 60 dimensional restricted or exceptional geometry. It is proved that the supersymmetry variations of D=11 supergravity, truncated to d=7, can be reproduced from this exceptional geometry in the expected manner. Secondly, Borisov's and Ogievetsky's procedure to construct a theory with diffeomorphism covariance from the joint non-linear realization of the affine linear subgroup of diffeomorphisms with the conformal one is reviewed in detail, which is then extended by discussing torsion in this context.
