Conservative and non-conservative methods based on hermite weighted essentially-non-oscillatory reconstruction for Vlasov equations [PDF]

open access: yes, 2013
We introduce a WENO reconstruction based on Hermite interpolation both for semi-Lagrangian and finite difference methods. This WENO reconstruction technique allows to control spurious oscillations.

Finite Difference Schemes as Algebraic Correspondences between Layers

open access: yesEPJ Web of Conferences, 2018
For some differential equations, especially for Riccati equation, new finite difference schemes are suggested. These schemes define protective correspondences between the layers.

A Priori Estimation of a Time Step for Numerically Solving Parabolic Problems

open access: yesMathematical Modelling and Analysis, 2015
This work deals with the problem of choosing a time step for the numerical solution of boundary value problems for parabolic equations. The problem solution is derived using the fully implicit scheme, whereas a time step is selected via explicit ...

Stability of Finite Difference Schemes to Pseudo-Hyperbolic Telegraph Equation

open access: yesJournal of Mathematical Sciences and Modelling, 2022
Hyperbolic partial differential equations are frequently referenced in modeling real-world problems in mathematics and engineering. Therefore, in this study, an initial-boundary value issue is proposed for the pseudo-hyperbolic telegraph equation.

Non-standard and Numerov finite difference schemes for finite difference time domain method to solve one-dimensional Schrödinger equation

open access: yesJournal of Physics: Theories and Applications, 2018
The purpose of  this paper is to show some improvements of the finite-difference time domain (FDTD) method using Numerov and non-standard finite difference (NSFD) schemes for solving the one-dimensional Schrödinger equation.

Higher order finite difference schemes for the magnetic induction equations [PDF]

open access: yes, 2010
We describe high order accurate and stable finite difference schemes for the initial-boundary value problem associated with the magnetic induction equations. These equations model the evolution of a magnetic field due to a given velocity field.

Domain decomposition finite element/finite difference method for the conductivity reconstruction in a hyperbolic equation

open access: yes, 2015
We present domain decomposition finite element/finite difference method for the solution of hyperbolic equation. The domain decomposition is performed such that finite elements and finite differences are used in different subdomains of the computational ...
