作为物体的场:时空和内部规范对称性的统一表示

Fields as Bodies: a unified presentation of spacetime and internal gauge symmetry

David Wallace

摘要:

利用场论的参数化表示(其中场的一部分在时空中的位置本身由从基流形到闵可夫斯基时空的映射表示),我证明了在局部和全局情况下,内部(杨-米尔斯型)和时空(庞加莱)对称性可以被精确地同等对待,因此引力理论可以被看作是完全标准意义上的规范理论。

英文摘要:

Using the parametrised representation of field theory (in which the location in spacetime of a part of a field is itself represented by a map from the base manifold to Minkowski spacetime) I demonstrate that in both local and global cases, internal (Yang-Mills-type) and spacetime (Poincaré) symmetries can be treated precisely on a par, so that gravitational theories may be regarded as gauge theories in a completely standard sense.
