Theoretical analysis of a finite-volume scheme for a stochastic Allen-Cahn problem with constraint

Caroline Bauzet, Cédric Sultan, Guy Vallet +1

The aim of this contribution is to address the convergence study of a time and space approximation scheme for an Allen-Cahn problem with constraint and perturbed by a multiplicativ…

Stochastic pseudomonotone parabolic obstacle problem: well-posedness Lewy-Stampacchia's inequalities

Niklas Sapountzoglou, Yassine Tahraoui, Guy Vallet +1

We consider obstacle problems for nonlinear stochastic evolution equations. More precisely, the leading operator in our equation is a nonlinear, second order pseudomonotone operato…

Stochastic parabolic equations in Musielak-Orlicz spaces with discontinuous in time N-function

Piotr Gwiazda, Jakub Woźnicki, Aneta Wróblewska-Kamińska +1

We consider a stochastic parabolic partial differential equation with Dirichlet boundary conditions, multiplicative stochastic noise, and a monotone parabolic operator A. The growt…

Convergence rates for a finite volume scheme of the stochastic heat equation

Niklas Sapountzoglou, Aleksandra Zimmermann

In this contribution, we provide convergence rates for a finite volume scheme of the stochastic heat equation with multiplicative Lipschitz noise and homogeneous Neumann boundary c…

Well-posedness of a time discretization scheme for a stochastic p-Laplace equation with Neumann boundary conditions

Caroline Bauzet, Kerstin Schmitz, Cédric Sultan +1

In this contribution, we are interested in the analysis of a semi-implicit time discretization scheme for the approximation of a parabolic equation driven by multiplicative colored…

A nonlinear stochastic diffusion-convection equation with reflection

Niklas Sapountzoglou, Yassine Tahraoui, Guy Vallet +1

We study a nonlinear, pseudomonotone, stochastic diffusion-convection evolution problem on a bounded spatial domain, in any space dimension, with homogeneous boundary conditions an…
