Isometric, symmetric and isosymmetric commuting $d$ -tuples of Banach space operators

Bhagwati Prashad Duggal, In Hyun Kim

Generalising the definition to commuting $d$ -tuples of operators, a number of authors have considered structural properties of $m$ -isometric, $n$ -symmetric and $(m, n)$ -isosymmetric…

Weakly Supercyclic Power Bounded Operators of Class C_{1.}

C. S. Kubrusly, B. P. Duggal

There is no supercyclic power bounded operator of class $C_{1 \cdot} .$ There exist, however, weakly l-sequentially supercyclic unitary operators $.$ We show that if $T$ i…

Tensor product of left polaroid operators

Enrico Boasso, B. P. Duggal

A Banach space operator $T \in B (X)$ is left polaroid if for each $λ \in iso σ_{a} (T)$ there is an integer $d (λ)$ such that asc $(T - λ) = d (λ) < \infty$ and $(T - λ)^{d (λ) + 1} X$ is closed…
