Range-Kernel Complementation
C. S. Kubrusly
If a Banach-space operator has a complemented range, then its normed-space adjoint has a complemented kernel and the converse holds on a reflexive Banach space. It is also shown wh…
Denseness of Sets of Supercyclic Vectors
C. S. Kubrusly
The sets of strongly supercyclic, weakly l-sequentially supercyclic, weakly sequentially supercyclic, and weakly supercyclic vectors for an arbitrary normed-space operator are all…
On Weak Supercyclicity II
C. S. Kubrusly, B. P. Duggal
This paper considers weak supercyclicity for bounded linear operators on a normed space. On the one hand, weak supercyclicity is investigated for classes of Hilbert-space operators…
On Weak Supercyclicity I
C. S. Kubrusly, B. P. Duggal
This paper provides conditions (i) to distinguish weak supercyclicity form supercyclicity for operators acting on normed and Banach spaces, and also (ii) to ensure when weak superc…
