Abstract:
We develop the Kaluza-Klein program from scratch, assuming no prior
knowledge of supergravity. We specialize to the compactification of 11-dimensional
supergravity on S4 to 7-dimensional anti de Sitter supergravity.
We discuss the general theory of spherical harmonics on coset manifolds,
and end with the full nonlinear dimensional reduction.
