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…

Spectral enclosure estimates for non-self-adjoint Dirac operators

Jeffrey Oregero

We study the spectrum of a periodic non-self-adjoint Dirac operator, and its dependence on a semiclassical parameter is also considered. Several bounds on the spectrum are obtained…

Experimental observation of the spatio-temporal dynamics of breather gases in a recirculating fiber loop

François Copie, Gino Biondini, Jeffrey Oregero +3

We report the first experimental observation of breather gases (BGs) in optics, realized in a recirculating fiber loop enabling virtually lossless propagation over km. Initi…

On the Modulation of Wave Trains in the Ostrovsky Equation

Mathew A. Johnson, Jeffrey Oregero, Wesley R. Perkins

We consider the nonlinear wave modulation of arbitrary amplitude periodic traveling wave solutions of the Ostrovsky equation, which arises as a model for the unidirectional propaga…

Modulational Stability of Wave Trains in the Camassa-Holm Equation

Mathew A. Johnson, Jeffrey Oregero

In this paper, we study the nonlinear wave modulation of arbitrary amplitude periodic traveling wave solutions of the Camassa-Holm (CH) equation. Slow modulations of wave trains is…
