Nonlinear stochastic systems theory and applications to physics.

*(English)*Zbl 0659.93003This monograph is devoted to the decomposition method developed by the author. The theoretical basis is presented in the first part: A summary of the decomposition method. The application of the method to various problems includes: Burger’s equation; nonlinear oscillations in physical systems; KdV equation; Benjamin-Ono equation; nonlinear Schrödinger equation and generalized Schrödinger equation; nonlinear plasmas; Tricomi problem; initial value problem for the wave equation; nonlinear dispersive or dissipative waves; nonlinear Klein-Gordon equation; analysis of model equations of gas dynamics; a new approach to the Effiger model for nonlinear quantum theory for gravitating particles; Navier-Stokes equations.

The book is written for the applied mathematicians and for persons interested in solving real, physical problems. Some numerical results are included, in order to compare the author’s method with other approximation methods. The author’s method appears to work well but the theoretical foundations still leave much to be explored, thus posing a fascinating challenge. It seems that the method can be automatized through symbolic programming.
