Subspaces that can and cannot be the kernel of a bounded operator on a Banach space

Niels Jakob Laustsen, Jared T. White

Given a Banach space $E$ , we ask which closed subspaces may be realised as the kernel of a bounded operator $E \to E$ . We prove some positive results which imply in particu…

Left ideals of Banach algebras and dual Banach algebras

Jared T. White

We investigate topologically left Noetherian Banach algebras. We show that if $G$ is a compact group, then $L^{1} (G)$ is topologically left Noetherian if and only if $G$ is metr…

The radical of the bidual of a Beurling algebra

Jared T. White

We prove that the bidual of a Beurling algebra on $Z$ , considered as a Banach algebra with the first Arens product, can never be semisimple. We then show that ${\rm rad\,}…
