Operators $\alpha $-commuting with a compact operator [PDF]

Proceedings of the American Mathematical Society, 1997
Summary: We update a question raised by Pearcy and Shields ('74) concerning the invariant subspace problem on Hilbert spaces.

About Riesz theory of compact operators

Bibechana, 2012
In this paper, it is shown that every compact operators are bounded and continuous. The bounded and continuous properties of an operator is sufficient for a Riesz operator.

Lipschitz Operators Associated with Weakly $p$-Compact and Unconditionally $p$-Compact Sets

Journal of Advanced Research in Natural and Applied Sciences
The study introduces different categories of Lipschitz operators linked with weakly $p$-compact and unconditionally $p$-compact sets. It explores some properties of these operator classes derived from linear operators associated with these sets and ...

Multiplication operators on the Banach algebra of bounded Φ-variation functions on compact subsets of ℂ

Demonstratio Mathematica, 2022
Let AΦ(K){{\mathbb{A}}}_{\Phi }\left({\bf{K}}) be the Banach algebra of bounded Φ\Phi -variation functions defined on a compact set K{\bf{K}} in the complex plane, hh a function defined on K{\bf{K}}, and Mh{M}_{h} a multiplication operator induced by hh.

New Characterizations of the Jeribi Essential Spectrum

International Journal of Analysis and Applications, 2023
In this paper, we give several characterizations of the Jeribi essential spectrum of a bounded linear operator defined on a Banach space by using the notion of almost weakly compact operators.

The relation between b-weakly compact operator and KB-operator

, 2019
Our aim is to solve the problem asked by Bahramnezhad and Azar in "KB-operators on Banach lattices and their relationships with Dunford-Pettis and order weakly compact operators". We show that a continuous operator R from a Banach lattice N into a Banach

Invariant subspace problem and compact operators on non-Archimedean Banach spaces

Extracta Mathematicae, 2020
In this paper, the invariant Subspace Problem is studied for the class of non-Archimedean compact operators on an infinite-dimensional Banach space E over a nontrivial complete non-Archimedean valued field K.

Boundary representations of operator spaces, and compact rectangular matrix convex sets [PDF]

, 2016
We initiate the study of matrix convexity for operator spaces. We define the notion of compact rectangular matrix convex set, and prove the natural analogs of the Krein--Milman and the bipolar theorems in this context.

Paclitaxel induces NM2‐dependent cellular contraction through GEF‐H1 dissociation from microtubules and RhoA/ROCK activation in cancer cells

Molecular Oncology, EarlyView.
Taxanes are widely used chemotherapeutics whose effects on cellular mechanics remain poorly understood. We show that paclitaxel induces rapid cellular contraction by promoting GEF‐H1 dissociation from microtubules and non‐muscle myosin II activation through RhoA/ROCK.
