Description
First a short reminder of the Kaluza-Klein programme and a review of the Coset Space Dimensional Reduction of higher dimensional gauge theories will be given. Then the "fuzzy sphere" will be presented, as a respresentative example of a non commutative coset as well as the construction of gauge theories on such spaces. Eventually examples will be presented of (a) a higher dimensional Unified Theory with fuzzy coset spaces as extra dimensions (b) gravity as a gauge theory on non commutative spaces.
