Abstract

After recalling briefly the connection between spontaneous symmetry breaking and off-diagonal long range order for models of magnets a general proof of spontaneous breaking of gauge symmetry as a consequence of Bose-Einstein Condensation is presented. The proof is based on a rigorous validation of Bogoliubov's cc-number substitution for the k=0{\bf k}={\bf 0} mode operator a0a_{\bf 0}.
