We consider two possible space-time manifolds: 1) V 4⊗ S 1⊗ S 2 where isospin doublets are identified with spinors; 2) V 4⊗ S 1⊗ S 3 in which both quarks and leptons doublets can be recast into the same spinor, such that the equal number of quark generations and leptonic families is explained. Finally a self-interacting complex scalar field is introduced to reproduce the spontaneous symmetry breaking mechanism; in this respect, at the end, we get an Higgs fields whose two components have got opposite hypercharges.
