ABSTRACT:

Many results on the Riemannian submersions are relevant in various areas of mathematical physics as Kaluza-Klein theories, Yang-Mills equations, strings, supergravity. Interest in higher dimensional theories has been ignited once again in recent years due largely to the discovery that the underlying symmetry of the fundamental interactions is geometrical, local and gauged.
