Sub-critical well-posedness for the intermediate nonlinear Schrödinger equation on the line

Andreia Chapouto, Justin Forlano, Thierry Laurens

We continue our study of the well-posedness theory for the intermediate nonlinear Schrödinger equation (INLS). Firstly, we prove that INLS is locally well-posed in $H^s (\mathbb{R}…

Well-posedness for the periodic Intermediate nonlinear Schrödinger equation

Andreia Chapouto, Justin Forlano, Thierry Laurens

We study the well-posedness for the intermediate nonlinear Schrödinger equation (INLS) with periodic boundary conditions. Using a gauge transform, we obtain large data local well-…

Gauge transform for the Korteweg-de Vries equation and well-posedness below the -scale

Andreia Chapouto, Simão Correia, João Pedro Ramos

We propose a new formulation of the Korteweg-de Vries equation (KdV) on the real line, via a gauge transform. While KdV and the gauged equation are equivalent for smooth solutions,…

On the well-posedness of the intermediate nonlinear Schrödinger equation on the line

Andreia Chapouto, Justin Forlano, Thierry Laurens

We consider a family of intermediate nonlinear Schrödinger equations (INLS) on the real line, which includes the continuum Calogero-Moser models (CCM). We prove that INLS is local…

A continuum of invariant measures for the periodic KdV and mKdV equations

Andreia Chapouto, Justin Forlano

We consider the real-valued defocusing modified Korteweg-de Vries equation (mKdV) on the circle. Based on the complete integrability of mKdV, Killip-Vişan-Zhang (2018) discovered…
