Central Limit Theorem for Temporal Average of Backward Euler-Maruyama Method

Journal of Computational Mathematics
This work focuses on the temporal average of the backward Euler-Maruyama (BEM) method, which is used to approximate the ergodic limit of stochastic ordinary differential equations (SODEs). We give the central limit theorem (CLT) of the temporal average of the BEM method, which characterizes its asymptotics in distribution.

Almost Surely Exponential Stability of Numerical Solutions for Stochastic Pantograph Equations

Abstract and Applied Analysis, 2014
Our effort is to develop a criterion on almost surely exponential stability of numerical solution to stochastic pantograph differential equations, with the help of the discrete semimartingale convergence theorem and the technique used in stable analysis ...

The robust finite-volume schemes for modeling nonclassical surface reactions

Nonlinear Analysis, 2018
A coupled system of nonlinear parabolic PDEs arising in modeling of surface reactions with piecewise continuous kinetic data is studied. The nonclassic conjugation conditions are used at the surface of the discontinuity of the kinetic data.

Distributed Newton method for time-varying convex optimization with backward Euler prediction

AIMS Mathematics
<p>We investigated the challenge of unconstrained distributed optimization with a time-varying objective function, employing a prediction-correction approach. Our method introduced a backward Euler prediction step that used the differential information from consecutive moments to forecast the trajectory's future direction.

An expanded mixed covolume element method for integro-differential equation of Sobolev type on triangular grids

Advances in Difference Equations, 2017
The expanded mixed covolume Element (EMCVE) method is studied for the two-dimensional integro-differential equation of Sobolev type. We use a piecewise constant function space and the lowest order Raviart-Thomas ( RT 0 $\mathit{RT}_{0}$ ) space as the ...

Spectral element discretization of the time-dependent Stokes problem with nonstandard boundary conditions

Boundary Value Problems
This work deals with the spectral element discretization of the time-dependent Stokes problem in two- and three-dimensional domains. The boundary condition is defined on the normal component of the velocity and the tangential components of the vorticity.
