Standing Wave Solutions in Twisted Multicore Fibers

Ross Parker, Alejando Aceves

In the present work, we consider the existence and spectral stability of standing wave solutions to a model for light propagation in a twisted multi-core fiber with no gain or loss…

The Stability of the -family of Peakon Equations

Efstathios G. Charalampidis, Ross Parker, Panayotis G. Kevrekidis +1

In the present work we revisit the -family model of peakon equations, containing as special cases the (Camassa-Holm) and (Degasperis-Procesi) integrable examples. We…

Existence and spectral stability of multi-pulses in discrete Hamiltonian lattice systems

Ross Parker, P. G. Kevrekidis, Björn Sandstede

In the present work, we consider the existence and spectral stability of multi-pulse solutions in Hamiltonian lattice systems. We provide a general framework for the study of such…

A reformulated Krein matrix for star-even polynomial operators with applications

Todd Kapitula, Ross Parker, Björn Sandstede

In its original formulation the Krein matrix was used to locate the spectrum of first-order star-even polynomial operators where both operator coefficients are nonsingular. Such op…
