Solutions to these equations are represented as polynomials of finite degree. Applicability of direct numerical methods to solving such problems with isometric and completely continuous operators, is proven. A two-sided method for finding the eigen-values of nonlinear operator equations, based on the variational representation of spectrum by the generalized Rayleigh’s functional, is proposed. The developed methods and their modifications are applied to certain problems. Product Description popup.authors popup.nrat_date 2020-04-02 Close
