Original versionProperties of Paley–Wiener spaces: sampling sets, contractions, and geometry of the unit ball by Ilia Zlotnikov, Stavanger : University of Stavanger, 2023 (PhD thesis UiS, no. 689)
This Thesis is based on five papers, four of which are published and one has been submitted for publication. For convenience of the reader, we also include one chapter that contains a brief overview of the results, some relevant background material, and comments on methods used in the proofs. The Thesis studies several problems from modern Harmonic analysis. More precisely, we focus on studying various properties of Paley-Wiener spaces: sampling sets, extreme and exposed points of the unit ball, and contraction operators.
