On selfadjoint extensions of semigroups of partial isometries
Janez Bernik, Laurent W. Marcoux, Alexey I. Popov +1
Let be a semigroup of partial isometries acting on a complex, infinite-dimensional, separable Hilbert space. In this paper we seek criteria which will guarantee that t…
Spectral conditions on Lie and Jordan algebras of compact operators
Matthew Kennedy, Heydar Radjavi
We investigate the properties of bounded operators which satisfy a certain spectral additivity condition, and use our results to study Lie and Jordan algebras of compact operators.…
Transitive spaces of operators
K. R. Davidson, L. W. Marcoux, H. Radjavi
We investigate algebraic and topological transitivity and, more generally, k-transitivity for linear spaces of operators. In finite dimensions, we determine minimal dimensions of k…
On the topological stable rank of non-selfadjoint operator algebras
K. R. Davidson, R. Levene, L. W. Marcoux +1
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 amon…
