PARACONTROLLED DISTRIBUTIONS AND SINGULAR PDES
We introduce an approach to study certain singular partial differential equations (PDEs) which is based on techniques from paradifferential calculus and on ideas from the theory of controlled rough paths.

On the stability of stationary solutions of a linear integro‐differential equation
In this paper the following two connected problems are discussed. The problem of the existence of a stationary solution for the abstract equation εx"(t)+x′(t)=Ax(t)+∫−∞tE(t−s)x(s)ds+ξ(t),t∈R containing a small parameter ε in Banach space B is considered. Here A ∈ ℒ(B) is a fixed operator, E ∈ C([0, +∞), ℒ(B)) and ξ is a stationary process.

Galerkin approximation and the strong solution of the Navier‐Stokes equation
We consider a stochastic equation of Navier‐Stokes type containing a noise part given by a stochastic integral with respect to a Wiener process. The purpose of this paper is to approximate the solution of this nonlinear equation by the Galerkin method. We prove the convergence in mean square.

Periodic in distribution solution for a telegraph equation
In this paper we study an abstract stochastic equation of second order and stochastic boundary problem for the telegraph equation in a strip. We prove the existence of solutions, which are d‐periodic (periodic in distribution) random processes.

A CLASS OF GROWTH MODELS RESCALING TO KPZ
We consider a large class of $1+1$-dimensional continuous interface growth models and we show that, in both the weakly asymmetric and the intermediate disorder regimes, these models converge to Hopf–Cole solutions to the KPZ equation.

A non‐nonstandard proof of Reimers′ existence result for heat SPDEs
In 1989, Reimers gave a nonstandard proof of the existence of a solution to heat SPDEs, driven by space‐time white noise, when the diffusion coefficient is continuous and satisfies a linear growth condition. Using the martingale problem approach, we give a non‐nonstandard proof of this fact, and with the aid of Girsanov′s theorem for continuous ...
