From the introduction: Additive difference schemes for first- and second-order differential-operator equations are constructed in the general case of additive splitting with an arbitrary number of mutually noncommuting operator terms. The construction of unconditionally stable schemes is based on regularization of a simplest explicit two- or three-layer scheme by a small multiplicative perturbation of each splitting operator. This approach covers the basic classes of nonstationary problems of mathematical physics.
