N Burq, N Tzvetkov - Inventiones mathematicae, 2008 - Springer
We prove that the subquartic wave equation on the three dimensional ball Θ, with Dirichlet
boundary conditions admits global strong solutions for a large set of random supercritical …

Enhanced dissipation, hypoellipticity, and anomalous small noise inviscid limits in shear flows

J Bedrossian, M Coti Zelati - Archive for Rational Mechanics and Analysis, 2017 - Springer
We analyze the decay and instant regularization properties of the evolution semigroups
generated by two-dimensional drift-diffusion equations in which the scalar is advected by a …

Invariant measures for the defocusing nonlinear Schrödinger equation

N Tzvetkov - Annales de l'Institut Fourier, 2008 - numdam.org
In [12], we constructed and proved the invariance of a Gibbs measure associated to the sub-
cubic, focusing or defocusing Nonlinear Schrödinger equation (NLS) on the disc of the plane …

Global approximate controllability for Schrödinger equation in higher Sobolev norms and applications

V Nersesyan - Annales de l'Institut Henri Poincaré C, Analyse Non …, 2010 - Elsevier
We prove that the Schrödinger equation is approximately controllable in Sobolev spaces Hs,
s> 0, generically with respect to the potential. We give two applications of this result. First, in …

Convergence of transport noise to Ornstein–Uhlenbeck for 2D Euler equations under the enstrophy measure

F Flandoli, D Luo - 2020 - projecteuclid.org
We consider the vorticity form of the 2D Euler equations which is perturbed by a suitable
transport type noise and has white noise initial condition. It is shown that stationary solutions …

Invariant measures for the nonlinear Schrodinger equation on the disc

N Tzvetkov - arXiv preprint math/0603112, 2006 - arxiv.org
We study Gibbs measures invariant under the flow of the NLS on the unit disc of $\R^ 2$. For
that purpose, we construct the dynamics on a phase space of limited Sobolev regularity and …

Ergodicity for a weakly damped stochastic non-linear Schrödinger equation

A Debussche, C Odasso - Journal of Evolution Equations, 2005 - Springer
We study a damped stochastic non-linear Schrödinger (NLS) equation driven by an additive
noise. It is white in time and smooth in space. Using a coupling method, we establish …

Exponential mixing for stochastic PDEs: the non-additive case

C Odasso - Probability theory and related fields, 2008 - Springer
We establish a general criterion which ensures exponential mixing of parabolic stochastic
partial differential equations (SPDE) driven by a non additive noise which is white in time …
