چکیده

Soit {u(t,x)}t≥0,x∈Rd la solution d’une équation de chaleur stochastique non-linéaire d-dimensionnelle, perturbée par un bruit gaussien, blanc en temps et avec une covariance homogène espace donnée mesure Borel finie qui satisfait condition Dalang. Nous démontrons deux théorèmes limite centrale fonctionnels pour des champs d’occupation forme N−d∫Rdg(u(t,x))ψ(x/N)dx quand N→∞, où g est function lipschitzienne sur Rd ψ∈L2(Rd). La preuve utilise inegalités type Poincaré, le calcul Malliavin, arguments compacité caractérisation du mouvement brownien comme seul processus Lévy continu moyenne nulle. Notre résultat généralise les Huang al (Stochastic Process. Appl. 131 (2020) 7170–7184 ; Stoch. Partial Differ. Equ., Anal. Computat. 8 402–421) sont valables lorsque g(u)=u ψ=1[0,1]d.

Postprocessing for Stochastic Parabolic Partial Differential Equations

We investigate the strong approximation of stochastic parabolic partial differential equations with additive noise. We introduce post-processing in the context of a standard Galerkin approximation, although other spatial discretizations are possible. In time, we follow [20] and use an exponential integrator. We prove strong error estimates and discuss the best number of postprocessing terms to ...

Solving parabolic stochastic partial differential equations via averaging over characteristics

The method of characteristics (the averaging over the characteristic formula) and the weak-sense numerical integration of ordinary stochastic differential equations together with the Monte Carlo technique are used to propose numerical methods for linear stochastic partial differential equations (SPDEs). Their orders of convergence in the mean-square sense and in the sense of almost sure converg...

Numerical Approximation of Parabolic Stochastic Partial Differential Equations

The topic of the talk were the time approximation of quasi linear stochastic partial differential equations of parabolic type. The framework were in the setting of stochastic evolution equations. An error bounds for the implicit Euler scheme was given and the stability of the scheme were considered.

Quasilinear Parabolic Stochastic Partial Differential Equations: Existence, Uniqueness

In this paper, we provide a direct approach to the existence and uniqueness of strong (in the probabilistic sense) and weak (in the PDE sense) solutions to quasilinear stochastic partial differential equations, which are neither monotone nor locally monotone.
