Numerical approximation of the long time behavior of a stochastic differential equation (SDE) is considered. Error estimates for time-averaging estimators are obtained and then used to show that the stationary behavior of the numerical method converges to that of the SDE. The error analysis is based on using an associated Poisson equation for the underlying SDE. The main advantages of this approach are its simplicity and universality. It works equally well for a range of explicit and implicit… 
Simplest random walk for approximating Robin boundary value problems and ergodic limits of reflected diffusions
It is proved that the simple-to-implement weak-sense numerical method to approximate reflected stochastic differential equations (RSDEs) has the first order of weak convergence and can be used to numerically solve linear parabolic and elliptic PDEs with Robin boundary condition.
Numerical Approximations to the Stationary Solutions of Stochastic Differential Equations
This paper starts with the random dynamical system generated by the SDE with the multiplicative noise and proves that the pullback flow has a stationary point; however, the stationary point is not constructible explicitly; therefore, the numerical approximation is looked at.
Asymptotic behavior of multiscale stochastic partial differential equations
In this paper, we study the asymptotic behavior of a semi-linear slow-fast stochastic partial differential equation with singular coefficients. Using the Poisson equation in Hilbert space, we first
Approximation of Invariant Measures for Stochastic Differential Equations with Piecewise Continuous Arguments via Backward Euler Method
The backward Euler (BE) method is applied to the equation, and it is proved that the numerical solution at integer time is not only Markovian but also reproduces a unique numerical invariant measure.

A Stable Numerical Scheme for Stochastic Differential Equations with Multiplicative Noise
An explicit scheme for stiff SDEs with multiplicative noise is developed that preserves the almost sure stability of the solutions for any step-size, as well as the property of being distant from $0$.
Large time behaviors of upwind schemes and B-schemes for Fokker-Planck equations on ℝ by jump processes
This work revisits some standard schemes, including upwind schemes and some B-schemes, for linear conservation laws from the viewpoint of jump processes, and establishes the uniform exponential convergence to the steady states of these schemes.

Abstract. In order to characterize the fluctuation between the ergodic limit and the timeaveraging estimator of a full discretization in a quantitative way, we establish a central limit theorem for
Convergence of the likelihood ratio method for linear response of non-equilibrium stationary states
Numerical schemes for computing the linear response of steady-state averages with respect to a perturbation of the drift part of the stochastic differential equation based on the Girsanov change-of-measure theory are considered.

Perturbation theories for geometrically ergodic Markov chains and Markov processes are considered and applications are given to numerical approximations of a randomly impulsed ODE, an Ito stochastic differential equation (SDE), and a parabolic stochastics partial differential equation subject to space-time Brownian noise.
