Solution of Bernstein's Approximation Problem [PDF]
In his famous monograph on approximation theory [2], S. Bernstein initiated the study of the closure properties of sets of functions {unK(u) }I on the real line. It is supposed that K(u) is continuous on (, o ) and that unK(u) vanishes at u = ? o for each value of n.

An approximate solution for the time-fractional diffusion equation
In this paper, a numerical method based on a finite difference scheme is proposed for solving the time-fractional diffusion equation (TFDE). The TFDE is obtained from the standard diffusion equation by replacing the first-order time derivative with ...

The Approximate Solution of Some Plane Boundary Value Problems of the Moment Theory of Elasticity
We consider a two-dimensional system of differential equations of the moment theory of elasticity. The general solution of this system is represented by two arbitrary harmonic functions and solution of the Helmholtz equation.
