On the asymptotic wavenumber of spiral waves in $λ-ω$ systems

Abstract

In this paper we consider spiral wave solutions of a general class of $λ-ω$ systems with a small parameter $q$ and we prove that the asymptotic wavenumber of the spirals is a $\mathcal{C}^{\infty}$-flat function of the perturbation parameter $q$.
