Blow-up for the integrable defocusing Ablowitz-Ladik equation

Dirk Hennig, Nikos I. Karachalios, Dionyssios Mantzavinos +2

This work establishes finite-time blow-up for the completely integrable defocusing Ablowitz-Ladik equation on both infinite and finite lattices. We first establish local well-posed…

Local well-posedness of the higher-order nonlinear Schrödinger equation on the half-line: the case of two boundary conditions

Aykut Alkın, Dionyssios Mantzavinos, Türker Özsarı

We prove the local Hadamard well-posedness of the higher-order nonlinear Schrödinger equation with negative dispersion coefficient on the half-line under nonzero Dirichlet and Neum…

Interface problems of mixed spatial order

Dionyssios Mantzavinos, Ravindra Pethiyagoda, Dave Smith

We solve interface problems on the line between various constant coefficient linear evolution partial differential equations. Our prototypical examples are the heat, linear Schrödi…

The "good" Boussinesq equation on the half-line with Robin boundary conditions

Shivani Agarwal, Dionyssios Mantzavinos

We prove the local Hadamard well-posedness of the ``good'' Boussinesq equation formulated on the half-line with nonzero Robin boundary conditions. These boundary data involve the D…

On the proximal dynamics between integrable and non-integrable members of a generalized Korteweg-de Vries family of equations

Nikos I. Karachalios, Dionyssios Mantzavinos, Jeffrey Oregero

The distance between the solutions to the integrable Korteweg-de Vries (KdV) equation and a broad class of non-integrable generalized KdV (gKdV) equations is estimated in appropria…

A new approach for the analysis of evolution partial differential equations on a finite interval

Türker Özsarı, Dionyssios Mantzavinos, Konstantinos Kalimeris

We show that, for certain evolution partial differential equations, the solution on a finite interval can be reconstructed as a superposition of restrictions to $(0,\ell…
