Wavelets and boundary value probems Yunakovsky, A.D. 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.

Positive solutions of a three point boundary value problem Webb, J.R.L. 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.

Attractors of reaction-diffusion equations with nonmonotone nonlinearity Valero, J. 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.
