Laplacians on spheres

Abstract

Spheres can be written as homogeneous spaces G/HG/H for compact Lie groups in a small number of ways. In each case, the decomposition of L2(G/H)L^2(G/H) into irreducible representations of GG contains interesting information. We recall these decompositions, and see what they can reveal about the analogous problem for noncompact real forms of GG and HH.
