On generalized metrics of Vandermonde type
Wolf-Jürgen Beyn
In a series of papers in the 1960's, S. Gähler defined and investigated so-called m-metric spaces and their topological properties. An m-metric assigns to any tuple of m+1 element…

Angular spectra of linear dynamical systems in discrete time
Wolf-Jürgen Beyn, Thorsten Hüls
In this work we introduce the notion of an angular spectrum for a linear discrete time nonautonomous dynamical system. The angular spectrum comprises all accumulation points of lon…

Algebraic rates of stability for front-type modulated waves in Ginzburg Landau equations
Wolf-Jürgen Beyn, Christian Döding
We consider the stability of front-type modulated waves in the complex Ginzburg-Landau equation (CGL). The waves occur in the bistable regime (e.g. of the quintic CGL) and connect…
