Analysis of stability for stochastic delay integro-differential equations

open access: yesJournal of Inequalities and Applications, 2018
In this paper, we concern stability of numerical methods applied to stochastic delay integro-differential equations. For linear stochastic delay integro-differential equations, it is shown that the mean-square stability is derived by the split-step ...

Spectral discretization of the time-dependent Navier-Stokes problem with mixed boundary conditions

open access: yesAdvances in Nonlinear Analysis, 2022
In this work, we handle a time-dependent Navier-Stokes problem in dimension three with a mixed boundary conditions. The variational formulation is written considering three independent unknowns: vorticity, velocity, and pressure.

A method of line with improved accuracy for singularly perturbed parabolic convection–diffusion problems with large temporal lag

open access: yesResults in Applied Mathematics, 2021
A robust numerical scheme is proposed to solve singularly perturbed large time-delay parabolic convection–diffusion problems. For domain discretization, the backward-Euler method for the time derivative and Micken’s type discretization for the space ...

Backward Euler method for stochastic differential equations with non-Lipschitz coefficients

open access: yes, 2022
We study the traditional backward Euler method for $m$-dimensional stochastic differential equations driven by fractional Brownian motion with Hurst parameter $H > 1/2$ whose drift coefficient satisfies the one-sided Lipschitz condition. The backward Euler scheme is proved to be of order $1$ and this rate is optimal by showing the asymptotic error ...

Numerical solution of stiff system by backward Euler method

open access: yesApplied Mathematical Sciences, 2015
In this paper, a piecewise uniform mesh is constructed and used, in conjuction with Backward Euler method to form a new numerical method for solving a coupled first order stiff system of Ordinary Differential Equations(ODEs) with prescribed initial conditions.

Numerical integration methods and layout improvements in the context of dynamic RNA visualization

open access: yesBMC Bioinformatics, 2017
Background RNA visualization software tools have traditionally presented a static visualization of RNA molecules with limited ability for users to interact with the resulting image once it is complete. Only a few tools allowed for dynamic structures. One

Backward Euler type methods for parabolic integro-differential equations in Banach space [PDF]

open access: yesESAIM: Mathematical Modelling and Numerical Analysis, 1998
The authors consider the initial value problem \[ u_t +Au = \int_0^t B(t,s)u(s) ds +f(t) \quad\text{for} t\in [0,T],\;\text{with} u(0)=v, \] in a Banach space \(X\), where \(A\) is a closed linear operator with dense domain \(D(A)\), and \(B(t,s)\) is a smooth linear operator with \(D(B(t,s))\supset D(A)\) and such that \(Q(t,s)=A^{-1}B(t,s)\) and ...

Efficient Galerkin finite element methods for a time-fractional Cattaneo equation

open access: yesAdvances in Difference Equations, 2020
In this paper, we develop two efficient fully discrete schemes for solving the time-fractional Cattaneo equation, where the fractional derivative is in the Caputo sense with order in ( 1 , 2 ] $(1, 2]$ .

An algorithm for solving the Navier–Stokes problem with mixed boundary conditions

open access: yesBoundary Value Problems, 2022
We consider a time-dependent Navier–Stokes problem in dimension two and three provided with mixed boundary conditions. We propose an iterative algorithm and its implementation for resolving this considered problem.
