We consider a $p$-Laplace evolution problem with stochastic forcing on a bounded domain $D\subset\mathbb{R}^d$ with homogeneous Dirichlet boundary conditions for $1<p<\infty$. The additive noise term is given by a stochastic integral in the sense of Ito. The technical difficulties arise from the merely integrable random initial data $u_0$ under consideration. Due to the poor regularity of the initial data, estimates in $W^{1,p}_0(D)$ are available with respect to truncations of the solution… 

Renormalized solutions for stochastic $p$-Laplace equations with $L^1$-initial data: The multiplicative case

We consider a p-Laplace evolution problem with multiplicative noise on a bounded domain D ⊂ R with homogeneous Dirichlet boundary conditions for 1 < p < ∞. The random initial data is merely

On temporal regularity for strong solutions to stochastic $p$-Laplace systems

where S(ξ) := (κ+ |ξ|) ξ, ξ ∈ R , p ∈ [2,∞) and κ ≥ 0. In applications, the time and space regularity of solutions to (1.1) are of great importance. When designing numerical algorithms, the

An averaged space-time discretization of the stochastic p-Laplace system

A sampling algorithm is provided to construct the necessary random input in an e-cient way and two new space-time discretizations based on the approximation of time-averaged values are proposed.

This paper studies the Cauchy–Dirichlet problem associated with the equation \[ b(u)_t - {\operatorname{div}}\left( {| {\nabla u - K(b(u)){\bf e}} |^{p - 2} (\nabla u - K(b(u)){\bf e})} \right) +

Renormalized Solutions for Stochastic Transport Equations and the Regularization by Bilinear Multiplicative Noise

A linear stochastic transport equation with non-regular coefficients is considered. Under the same assumption of the deterministic theory, all weak L ∞-solutions are renormalized. But then, if the

In this paper we prove the existence and uniqueness of a renormalised solution of the nonlinear problem where the data f and u0 belong to L1(Ω × (0, T)) and L1 (Ω), and where the function a:(0, T) ×

We study the large-data Cauchy problem for Boltzmann equations with general collision kernels. We prove that sequences of solutions which satisfy only the physically natural a priori bounds converge

Well-posedness and regularity for quasilinear degenerate parabolic-hyperbolic SPDE

We study quasilinear degenerate parabolic-hyperbolic stochastic partial differential equations with general multiplicative noise within the framework of kinetic solutions. Our results are twofold:

We formulate a criterion for the existence and uniqueness of an invariant measure for a Markov process taking values in a Polish phase space. In addition, weak- * ergodicity, that is, the weak

In the paper, the concept of the Lévy process with values in a real separable Hilbert space is introduced and some of its properties, in particular the Lévy-Khinchin decomposition, is described.

Abstract. We consider the stochastic transport linear equation and we prove existence and uniqueness of weak Lp-solutions. Moreover, we obtain a representation of the general solution and a

We introduce a new notion of “regularity structure” that provides an algebraic framework allowing to describe functions and/or distributions via a kind of “jet” or local Taylor expansion around each
