On Expansive Mappings and Non-hypercyclicity
by Sichel, Edward Simon, M.S., California State University, Fresno, 2019, 74; 27664289
Abstract (Summary)

We take a close look at the nature of expansive mappings on certain metric spaces (compact, totally bounded, and bounded), provide a finer classification for such mappings, and use them to characterize boundedness. We also furnish a simple straightforward proof of the non-hypercyclicity of an arbitrary (bounded or not) normal operator in a complex Hilbert space as well as of a certain collection of its exponentials and establish non-hypercyclicity for symmetric operators.
