This e-book, because the convention, is prepared into 3 sections. part A describes the fashionable conception of effective cubature formulation; embedding theorems; and difficulties of spectral research. part B considers the theoretical questions of partial differential equations, with emphasis on hyperbolic equations and structures, formulations, and techniques for nonclassical difficulties of mathematical physics. part C addresses a number of the difficulties of numerical arithmetic, with specialize in the optimal and asymptotically optimal algorithms for fixing the issues of numerical mathematics.
