Higher-Dimensional Unification with continuous and fuzzy coset spaces as extra dimensions
We first review the Coset Space Dimensional Reduction (CSDR) programme and present the best model constructed so far based on the N = 1, 10-dimensional E_8 gauge theory reduced over the nearly-Kaehler manifold SU(3)=U(1)xU(1) with the additional use of the Wilsonflux mechanism. Then we present the corresponding programme in the case that the extra dimensions are considered to be fuzzy coset spaces, and the best model that has been constructed in this framework too. In both cases the best model appears to be the trinification GUT SU(3)^3.
