Isometric, symmetric and isosymmetric commuting -tuples of Banach space operators
Bhagwati Prashad Duggal, In Hyun Kim
Generalising the definition to commuting -tuples of operators, a number of authors have considered structural properties of -isometric, -symmetric and -isosymmetric…
Structure of -quasi left -invertible and related classes of operators
B. P. Duggal, I. H. Kim
Given Hilbert space operators $T, S\in\B$, let and $δ\in B(\B)$ denote the elementary operators and $δ_{T,S}(X)=(L_T-R_S)(X)=TX…
Structure of elementary operators defining -left invertible, -selfadjoint and related classes of operators
B. P. Duggal, I. H. Kim
We use elementary algebraic properties of left, right multiplication operators to prove some deep structural properties of left -invertible, -isometric, -selfadjoint and o…
On th roots of normal operators
B. P. Duggal, I. H. Kim
For -normal operators [2, 4, 5], equivalently -th roots of normal Hilbert space operators, both and satisfy the Bishop--Eschmeier--Putinar property ,…
