Using classic differential quadrature formulae and uniform grids, this paper systematically constructs a variety of high-order finite difference schemes, and some of these schemes are consistent with the so-called boundary value methods. The derived diffe... see more

In this paper, third and fourth order of accuracy stable difference schemes for approximately solving multipoint nonlocal boundary value problems for hyperbolic equations with the Neumann boundary conditions are considered. Stability estimates for the sol... see more

The exact solution of third order fractional partial differential equations is obtained depending on initial-boundary value problem. The exact solutions and theorem of stability estimates is presented for this equation. Difference schemes are constructed ... see more

A numerical model to simulate the process of pollutant transfer in rooms was developed. The numerical simulation is carried out using 2D models of pollutant transfer and potential flow. The implicit finite difference schemes are used. The results of numer... see more

The main parameters characterizing the process of deformation of solids are displacements, strain and stress tensors. From the point of view of the strength and reliability of the structure and its elements, researchers and engineers are mainly interested... see more

This paper is concerned with a high-order finite difference scheme for a nonlocal boundary value problem of parabolic equation the integral in the boundary equation is approximated by the Simpson rule numerical experiments show that the approximate soluti... see more

In this paper an initial value problem for a non-linear system of two singularly perturbed first order differential equations is considered on the interval (0,1].The components of the solution of this system exhibit initial layers at 0. A numerical method... see more

In this paper an initial value problem for asemi-linear system of two singularly perturbed first order delay differential equations is considered on the interval(0,2]. The components of the solution of this system exhibit initial layers at 0 and interior ... see more
