An effective action for gauge theories of general form is constructed in the framework of the Lagrangian approach on the basis of the unitarity condition for the $S$ matrix. Necessary conditions for the existence of a unitary $S$ matrix are formulated. An explicit expression for the effective action is obtained for a large class of physically interesting theories, including Yang–Mills fields, an antisynnnetric tensor field, and string field theory.
