A compact finite difference scheme with absorbing boundary condition for forced KdV equation [PDF]

open access: yesMethodsX, 2023
Studying the long-time solution behavior of the Korteweg-de Vries (KdV) type equation with a periodic force acting at one end of the long channel is important for simulating the blood flow in artery driven by heart pulses.

New solvability condition of 2-d nonlocal boundary value problem for Poisson’s operator on rectangle [PDF]

open access: yesE-Journal of Analysis and Applied Mathematics, 2021
Differential and difference interpretations of a nonlocal boundary value problem for Poisson’s equation in open rectangular domain are studied. New solvability conditions are obtained in respect of existence, uniqueness and a priori estimate of the ...

On differential approximations of difference schemes [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The concept of the first differential approximation was introduced in the 1950s for the analysis of difference schemes by A. I. Zhukov  and then was used to study the quality of difference schemes approximating equations in partial derivatives.

Boundedness of dispersive difference schemes [PDF]

open access: yesMathematics of Computation, 1990
The pointwise behavior of dispersive difference schemes for the simple wave equation in one dimension is analyzed. If the initial data are in certain Besov spaces, the scheme is shown to be pointwise unbounded. Boundedness is shown when the initial data are of bounded variation.
