On the continuous resonant equation for NLS: II. Statistical study [PDF]

open access: yes, 2015
We consider the continuous resonant (CR) system of the 2D cubic nonlinear Schr{\"o}dinger (NLS) equation. This system arises in numerous instances as an effective equation for the long-time dynamics of NLS in confined regimes (e.g. on a compact domain or

Low regularity well-posedness of KP-I equations: the three-dimensional case [PDF]

open access: yes, 2022
In this paper, low regularity local well-posedness results for the Kadomtsev–Petviashvili–I equation posed in spatial dimension $d=3$ are proved. Periodic, non-periodic and mixed settings as well as generalized dispersion relations are considered. In the

Invariant Measures for Dissipative Dynamical Systems: Abstract Results and Applications [PDF]

open access: yes, 2012
In this work we study certain invariant measures that can be associated to the time averaged observation of a broad class of dissipative semigroups via the notion of a generalized Banach limit.

Multilinear Eigenfunction Estimates And Global Existence For The Three Dimensional Nonlinear Schr\"Odinger Equations [PDF]

open access: yes, 2005
We study nonlinear Schr\"odinger equations, posed on a three dimensional Riemannian manifold $M$. We prove global existence of strong $H^1$ solutions on $M=S^3$ and $M=S^2\times S^1$ as far as the nonlinearity is defocusing and sub-quintic and thus we ...

Random data Cauchy theory for supercritical wave equations II : A global existence result

open access: yes, 2007
We prove that the subquartic wave equation on the three dimensional ball $\Theta$, with Dirichlet boundary conditions admits global strong solutions for a large set of random supercritical initial data in $\cap_ ...

Energy scattering for 2D critical wave equation

open access: yes, 2008
We investigate existence and asymptotic completeness of the wave operators for nonlinear Klein-Gordon and Schr\"odinger equations with a defocusing exponential nonlinearity in two space dimensions. A certain threshold is defined based on the value of the

Bilinear dispersive estimates via space-time resonances, part II: dimensions 2 and 3

open access: yes, 2013
Consider a bilinear interaction between two linear dispersive waves with a generic resonant structure (roughly speaking, space and time resonant sets intersect transversally).

Nonlinear Waves and Dispersive Equations [PDF]

open access: yes, 2013
Nonlinear dispersive equations are models for nonlinear waves in a wide range of physical contexts. Mathematically they display an interplay between linear dispersion and nonlinear interactions, which can result in a wide range of outcomes from finite ...

Almost sure well-posedness of the cubic nonlinear Schr\"odinger equation below L^2(T) [PDF]

open access: yes, 2011
We consider the Cauchy problem for the one-dimensional periodic cubic nonlinear Schr\"odinger equation (NLS) with initial data below L^2. In particular, we exhibit nonlinear smoothing when the initial data are randomized.
