In this paper we develop a method for identifying SISO Wiener-type nonlinear systems, that is, systems consisting of a linear dynamic system followed by a static nonlinearity. Unlike previous techniques developed for Wiener system identification, our approach allows the identification of systems with nonlinearities that are known but not necessarily invertible, continuous, differentiable, or an...

We prove unique continuation principles for solutions of evolution Schrödinger equations with time dependent potentials. These correspond to uncertainly principles of Paley-Wiener type for the Fourier transform. Our results extends to a large class of semi-linear Schrödinger equation.

We study a Wiener process that is conditioned to pass through finite set of points and consider the dynamics generated by iterating sample path from this process. Using topological techniques we are able characterize global deduce existence, structure approximate location invariant sets. Most importantly, compute probability characterization correct. This work probabilistic in nature intended p...
