On Assignment of the Upper Bohl Exponent for Linear Time-Invariant Control Systems in a Hilbert Space by State Feedback

Vasilii Zaitsev, Marina Zhuravleva
2020 Mathematics  
We study the problem of arbitrary assignment for the upper Bohl exponent by state feedback control.  ...  We prove that if the open-loop system is exactly controllable then one can shift the upper Bohl exponent of the closed-loop system by any pregiven number with respect to the upper Bohl exponent of the  ...  In this paper, we studied the problem of arbitrary assignment of the upper Bohl exponent for continuous-time systems in an infinite-dimensional Hilbert space.  ...

Equidistribution, Uniform distribution: a probabilist's perspective [article]

Vlada Limic, Nedžad Limić
2018 arXiv   pre-print
One purpose of this note is to provide a short introduction for probabilists. We proceed by recalling a perspective originating in a work of the second author from 2002.  ...  The translation from number theory to probability language brings into focus a version of the strong law of large numbers for weakly correlated complex-valued random variables, the study of which was initiated  ...  We are both grateful to Christoph Aistleitner for detailed reading of the original preprint, and a number of valuable comments and suggestions.  ...

Lyapunov Exponents in the Spectral Theory of Primitive Inflation Systems

Using tools from the theory of Lyapunov exponents, we provide a sufficient criterion to rule out the presence of absolutely continuous components in the diffraction and a necessary condition to have a  ...  We show that this holds for large classes of systems, and, as a sanity check, show that the necessary criterion for existence is satisfied by systems which are a priori known to have absolutely continuous  ...  As in the one-dimensional examples, this upper bound can be calculated numerically up to a certain level of precision.  ...

Uniform Shadow Limit Reduction for Reaction-Diffusion-ODE Systems

Chris Kowall
The method is based on previous results for short-time intervals which use a cut-off technique applied to the system linearized at the shadow solution.  ...  The partial lack of diffusion implies low regularity in space of solutions to both systems. Hence, mild solutions are considered in this work.  ...  Nevertheless, using Bohl exponents as in [14, Corollary 4.2] for the subsystem of u, we obtain exponential stability of the corresponding evolution system U for some exponent η > 0.  ...
