A Hartman-Grobman theorem on Banach bundles
Benjamin Rogoll, Stefan Siegmund
We provide generalized linearization theorems for skew-product flows on abstract Banach bundles over locally compact metric spaces, allowing for a unified treatment of uniform and…
The new notion of Bohl dichotomy for nonautonomous difference equations and its relation to exponential dichotomy
Adam Czornik, Konrad Kitzing, Stefan Siegmund
Bohl dichotomy is a notion of hyperbolicity for linear nonautonomous difference equations that is weaker than the classical concept of exponential dichotomy. In the class of system…
Spectra based on Bohl exponents and Bohl dichotomy for nonautonomous difference equations
Adam Czornik, Konrad Kitzing, Stefan Siegmund
For nonautonomous linear difference equations with bounded coefficients on which have a bounded inverse, we introduce two different notions of spectra and discuss thei…
Maxwell's equations revisited -- mental imagery and mathematical symbols
Matthias Geyer, Jan Hausmann, Konrad Kitzing +2
Using Maxwell's mental imagery of a tube of fluid motion of an imaginary fluid, we derive his equations ,…
A Hilbert space approach to fractional differential equations
Kai Diethelm, Konrad Kitzing, Rainer Picard +3
We study fractional differential equations of Riemann-Liouville and Caputo type in Hilbert spaces. Using exponentially weighted spaces of functions defined on , we defi…
Asynchronous discrete dynamical systems
Stefan Siegmund, Petr Stehlik
We study two coupled discrete-time equations with different (asynchronous) periodic time scales. The coupling is of the type sample and hold, i.e., the state of each equation is sa…
