Scattering for the nonlinear Schrödinger equation with concentrated nonlinearity

Benjamin Harrop-Griffiths, Rowan Killip, Monica Visan

We consider the cubic defocusing nonlinear Schrödinger equation in one dimension with the nonlinearity concentrated at a single point. We prove global well-posedness in the scaling…

A priori bounds and equicontinuity of orbits for the intermediate long wave equation

Benjamin Harrop-Griffiths, Rowan Killip, Monica Visan

We prove uniform-in-time a priori $H^{s}$ bounds for solutions to the intermediate long wave equation posed both on the line and on the circle, covering the range $- \frac{1}{2} < s \leq 0$ .…

Homogenization for the nonlinear Schrödinger equation with sprinkled nonlinearity

Benjamin Harrop-Griffiths, Maria Ntekoume

We first prove homogenization for the nonlinear Schrödinger equation with sprinkled nonlinearity introduced in [19]. We then investigate how solutions fluctuate about the homogeniz…
