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…
Determining the source of period-doubling instabilities in spiral waves
Stephanie Dodson, Bjorn Sandstede
Spiral wave patterns observed in models of cardiac arrhythmias and chemical oscillations develop alternans and stationary line defects, which can both be thought of as period-doubl…
