Enclosure of the Numerical Range and Resolvent Estimates of Non-selfadjoint Operator Functions

Autor: Torshage, Axel

In this paper we discuss the relationship between the numerical range of an extensive class of unbounded operator functions and the joint numerical range of the operator coefficients. Furthermore, we derive methods on how to find estimates of the joi

On the topological stable rank of non-selfadjoint operator algebras

Autor: Davidson, K. R., Levene, R., Marcoux, L. W., Radjavi, H.

We provide a negative solution to a question of M. Rieffel who asked if the right and left topological stable ranks of a Banach algebra must always agree. Our example is found amongst a class of nest algebras. We show that for many other nest algebra

Non-selfadjoint Operator Algebras generated by Weighted Shifts on Fock Space

Autor: Kribs, David W.

Publikováno v: Houston J. Math., 30 (2004), 147-169.

Noncommutative multivariable versions of weighted shifts arise naturally as `weighted' left creation operators acting on Fock space. We investigate the unital weak operator topology closed algebras they generate. The unweighted case yields noncommuta
