A very interesting approach in the attempts to unify all the interactions is to consider that a .unification takes place in higher than four dimensions. The most ambitious program based on the old Kaluza-Klein[3] idea is not able to reproduce the low energy chiral nature of the weak interactions. Moreover it is not self consistent since the assumed space-time configurations cannot be solutions of the higher dimensional theory. A suggested way out was the introduction of Yang-Mills fields[4] in the higher dimensional theory. This solution, despite the fact that it is not as attractive as the original program, found a very natural role in superstring theories[5]. From the particle physics point of view the most important question is how such a theory behaves in four dimensions and in particular in low energies. Therefore most of our efforts concern studies of the properties of an attractive scheme, the Coset-Space-Dimensional-Reduction (C.S.D.R) scheme[6,7] which permits the study of the effective four dimensional theory coming from a gauge theory defined in higher dimensions.
