In this paper we carefully study the large time behaviour of u(t, x, y) := Ex,y f(Xt, Yt)− ∫ f dμ, where (Xt, Yt) is the solution of a stochastic Hamiltonian dissipative system with non gbally Lipschitz coefficients, μ its unique invariant law, and f a smooth function with polynomial growth at infinity. Our aim is to prove the exponential decay to 0 of u(t, x, y) and all its derivatives when t goes to infinity, for all (x, y) in R. We apply our precise estimates on u(t, x, y) to analyze the…

TLDR
The error induced by the substitution of X t with the solution X t,n of a convenient stochastic ordinary differential equation is characterized and the rate of convergence of E to E is established, where XT,n denotes the explicit Euler method.
ON GLOBAL ERROR OF SYMPLECTIC SCHEMES FOR STOCHASTIC HAMILTONIAN SYSTEMS
We investigate a first order weak symplectic numerical scheme for stochastic Hamiltonian systems. Given the solution (Xt) and a class of functions f , we derive the expansion of the global
Strong and weak divergence in finite time of Euler's method for stochastic differential equations with non-globally Lipschitz continuous coefficients
The stochastic Euler scheme is known to converge to the exact solution of a stochastic differential equation (SDE) with globally Lipschitz continuous drift and diffusion coefficients. Recent results
A Stable Numerical Scheme for Stochastic Differential Equations with Multiplicative Noise
TLDR
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 $0$.
Stochastic Variational Integrators
This paper presents a continuous and discrete Lagrangian theory for stochastic Hamiltonian systems on manifolds, akin to the Ornstein–Uhlenbeck theory of Brownian motion in a force field. The main
RATE OF ESTIMATION FOR THE STATIONARY DISTRIBUTION OF STOCHASTIC DAMPING HAMILTONIAN SYSTEMS WITH CONTINUOUS OBSERVATIONS
We study the problem of the non-parametric estimation for the density π of the stationary distribution of a stochastic two-dimensional damping Hamiltonian system (Z_t) t∈[0,T ] = (X_t, Y_t) t∈[0,T ].

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.

We study a class of ergodic stochastic control problems for diffusion processes. We describe the basic ideas concerning the Hamilton-Jacobi-Bellman equation. For a given class of control problems we

Markov Chains and Stochastic Stability
TLDR
This second edition reflects the same discipline and style that marked out the original and helped it to become a classic: proofs are rigorous and concise, the range of applications is broad and knowledgeable, and key ideas are accessible to practitioners with limited mathematical background.
