摘要：

We describe the Kaluza-Klein approach to general relativity of 4-dimensional spacetimes. This approach is based on the (2.2)-fibration of a generic 3-dimensional spacetime, which is viewed as a local product of a (1 + 1)-dimensional base manifold and a 2-dimensional fibre: space. It is shown that the metric coefficients can he decomposed into sets of fields, which transform as a tensor field, gauge fields, and scalar fields with respect to the infinite dimensional group of the diffeomorphisms of the 2-dimensional fibre space. We discuss a few applications of this formalism. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
