For an adequate description of real physics nonperturbative effects are inevitable. This book explains how these effects may be obtained in the framework of spontaneous generation of effective interactions.The method is based on N.N. Bogoliubov's conception of compensation equations. As a result, the principal features of the Standard Model and significant nonperturbative effects can be described, including recent results at the LHC& TEVATRON.
