Convergence of a semi-discrete scheme for the stochastic Korteweg-de Vries equation

open access: yesDiscrete & Continuous Dynamical Systems - B, 2006
In this article, we prove the convergence of a semi-discrete scheme applied to the stochastic Korteweg--de Vries equation driven by an additive and localized noise. It is the Crank--Nicholson scheme for the deterministic part and is implicit. This scheme was used in previous numerical experiments on the influence of a noise on soliton propagation [

Classification and image processing with a semi‐discrete scheme for fidelity forced Allen–Cahn on graphs [PDF]

open access: yesGAMM-Mitteilungen, 2020
This paper introduces a semi‐discrete implicit Euler (SDIE) scheme for the Allen‐Cahn equation (ACE) with fidelity forcing on graphs. The continuous‐in‐time version of this differential equation was pioneered by Bertozzi and Flenner in 2012 as a method ...

Second-Order Semi-Discretized Schemes for Solving Stochastic Quenching Models on Arbitrary Spatial Grids [PDF]

open access: yesDiscrete Dynamics in Nature and Society, 2021
Reaction-diffusion-advection equations provide precise interpretations for many important phenomena in complex interactions between natural and artificial systems. This paper studies second-order semi-discretizations for the numerical solution of reaction-diffusion-advection equations modeling quenching types of singularities occurring in numerous ...

An H1 -Galerkin Mixed Finite Element Approximation of a Nonlocal Hyperbolic Equation

open access: yesMathematical Modelling and Analysis, 2017
In this paper we investigate a semi-discrete H1 -Galerkin mixed finite element approximation of one kind of nolocal second order nonlinear hyperbolic equation, which is often used to describe vibration of an elastic string.

A Second Order Fully-discrete Linear Energy Stable Scheme for a Binary Compressible Viscous Fluid Model [PDF]

open access: yes, 2018
We present a linear, second order fully discrete numerical scheme on a staggered grid for a thermodynamically consistent hydrodynamic phase field model of binary compressible fluid flow mixtures derived from the generalized Onsager Principle.

Analysis of algebraic flux correction schemes for semi-discrete advection problems

open access: yesBIT Numerical Mathematics, 2023
AbstractBased on recent developments regarding the analysis of algebraic flux correction schemes, we consider a locally bound-preserving discretization of the time-dependent advection equation. Specifically, we analyze a monolithic convex limiting scheme based on piecewise (multi-)linear continuous finite elements in the semi-discrete formulation.
