Weak cluster points of maximizing sequences on Banach spaces satisfying
David Norrbo
Given a bounded linear operator on a separable Banach space with property , we prove that the smallest and the largest norm of weak cluster points of all maximizing sequ…
Weak null maximum and integration of families of multiplication operators
David Norrbo
Let be a reflexive Hardy space or weighted Bergman space on the unit disk in the complex plane. For a bounded linear operator on , let $\textrm{wem}(S):= \sup_{(f_n)} \l…
Essential norm and integration of a family of weighted composition operators
David Norrbo
We study the interchange of essential norm and integration of certain families of weighted composition operators acting on the standard weighted Bergman spaces , where $p>1…
Compactness and related properties of weighted composition operators on weighted BMOA spaces
David Norrbo
It is shown that a large class of properties coincide for weighted composition operators on a large class of weighted VMOA spaces, including the ones with logarithmic weights and t…
