RESUMO

We consider the results of computing experiments with mathematical models of modern problems of a panto-physical profile. Their solving yields new features, effects or phenomena in the nonlinear optics of multi-beam processes, dynamic holography and plasma physics. While computing experiments the systems approach to the problems of mathematical and physical interpretation of the results of experimental and theoretical investigations is used. This approach uses the techniques of linear and nonlinear integral equations, the theory of the spline-iterative methods of calculus physics, compares the results of computing and physical experiments.
