Description

Effective potential in an arbitrary non-renormalizable scalar field model in subleading order is calculated. Based on BPHZ-renormalization and Bogoliubov-Parasiuk theorem it is found formalism to construct generalization of usual renormalization group equations. Application of this formalism leads to efficient way of calculation quantum contribution to effective potential whether renormalizable it is or not
