Abstract
Definition of Feynman integrals as solutions of some well defined systems of differential equations is proposed. This definition is equivalent to usual one but needs no regularization and application of -operation. It is argued that proposed renormalization scheme maintains all symmetries that can be maintained in perturbative quantum field theory, and also is convenient for practical calculations.
