About this document
Besel Orbits of Normal Operators by vilma is a document available to read on EtoBox.
The paper investigates the conditions under which the sequence (Ak x)k∈N forms a Bessel sequence for a bounded normal operator A in a Hilbert space. It provides characterizations based on the spectral measure of A and explores special cases for unitary and selfadjoint operators. The findings are applied to the context of Dynamical Sampling, particularly in relation to the heat equation, concluding that certain sequences do not qualify as Bessel sequences.
