Smooth, Compact Operators [PDF]

Proceedings of the American Mathematical Society, 1979
It is a result of Holub’s [Math. Ann. 201 (1973), 157-163], that for T a compact operator on a real Hilbert space, T is smooth ⇔ ‖ T x 1 ‖ = ‖ T

On the Quotients of Regular Operators

Universal Journal of Mathematics and Applications, 2019
We give some results about quotients of regular operators on Banach lattices by the linear span of the positive M-weakly and positive L-weakly compact operators.

Global functional calculus for operators on compact Lie groups [PDF]

, 2014
In this paper we develop the functional calculus for elliptic operators on compact Lie groups without the assumption that the operator is a classical pseudo-differential operator. Consequently, we provide a symbolic descriptions of complex powers of such

Properties of Fuzzy Compact Linear Operators on Fuzzy Normed Spaces

مجلة بغداد للعلوم, 2019
In this paper the definition of fuzzy normed space is recalled and its basic properties. Then the definition of fuzzy compact operator from fuzzy normed space into another fuzzy normed space is introduced after that the proof of an operator is fuzzy ...

Some properties of weak Banach-Saks operators [PDF]

Mathematica Bohemica, 2021
We establish necessary and sufficient conditions under which weak Banach-Saks operators are weakly compact (respectively, {\rm L}-weakly compact; respectively, {\rm M}-weakly compact).

Global quantization of pseudo-differential operators on compact Lie groups, SU(2) and 3-sphere [PDF]

, 2008
Global quantization of pseudo-differential operators on compact Lie groups is introduced relying on the representation theory of the group rather than on expressions in local coordinates.

Analytic Families of Self-Adjoint Compact Operators Which Commute with Their Derivative

Communications in Advanced Mathematical Sciences, 2020
Spectral properties of analytic families of compact operators on a Hilbert space are studied. The results obtained are then used to establish that an analytic family of self-adjoint compact operators on a Hilbert space $\mathcal{H},$ which commute with ...

Compact operators in TRO’s [PDF]

Proceedings of the American Mathematical Society, 2012
We give a geometric characterization of the elements of a TRO that can be represented as compact operators by a faithful representation of the TRO.
