Method of determination of an approximate solution of a boundary value problem for the ordinary differential equation, based on an expansion by a system of basis functions, constructed on a multiscale system of basis wavelets and satisfying given boundary conditions is described.

We establish existence of positive solutions of some boundary value problems for a second order semilinear ordinary differential equation u" + g(t)f(u) = 0 on [0,1]. The boundary conditions involve three points, 0 ‹ η ‹ 1. The conditions on f strictly include the sub- and super-linear cases.

The Hele-Shaw problem has studied in the paper. Estimates of both solutions’ support and time of their existence have been obtained with the methods of symmetrized.

In this paper we study the existence of global compact attractors for nonlinear parabolic equations of reaction-diffusion type. The studied equations are generated by a difference of subdifferential maps and are not assumed to have a unique solution for each initial state. Applications are given to inclusions modelling combustion in porous media and processes of transmission of electrical impulses in nerve axons.
