%TInfrared behaviour of systems with Goldstone bosons
%XVarious nonperturbative techniques are given for handling the infrared behaviour of systems with Goldstone bosons. These include an explicit form for the generating functional of OPI-vertices of the O(N)-models in the large-N limit, analysis based on Ward identities, as well as a renormalisation group picture. Some consequences are discussed. ((orig.)).
