Analysis of an exponential integrator for stochastic PDEs driven by Riesz noise

Charles-Edouard BrÃ©hier, David Cohen, LluÃs Quer-Sardanyons +1

We present and study an explicit exponential integrator for parabolic SPDEs in any dimension driven by a Gaussian noise which is white in time and with spatial correlation given by…

Global well-posedness for hyperbolic SPDEs with non-Lipschitz coefficients driven by space-time LÃ©vy white noise

Raluca M. Balan, Juan J. JimÃ©nez, LluÃs Quer-Sardanyons

In this article, we study the global well-posedness of hyperbolic SPDEs on a bounded domain in $R^{d}$ , driven by a space-time LÃ©vy white noise, when the drift and diffusio…

Convergence in law for quasi-linear SPDEs

Maria Jolis, Salvador Ortiz-Latorre, LluÃs Quer-Sardanyons

We consider the quasi-linear stochastic wave and heat equations in $R^{d}$ with $d \in {1, 2, 3}$ and $d \geq 1$ , respectively, and perturbed by an additive Gaussian noise whi…
