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.

Weighted Composition Operators Between Extended Lipschitz Algebras on Compact Metric Spaces [PDF]
Sahand Communications in Mathematical Analysis, 2020 In this paper, we provide a complete description of weighted composition operators between extended Lipschitz algebras on compact metric spaces. We give necessary and sufficient conditions for the injectivity and the sujectivity of these operators.

Commutativity of normal compact operators via projective spectrum [PDF]
, 2016 In this note, we will study the commutativity of normal compact operators with strong Agmon's condition by using the projective spectrum. This generalizes the result in MR3449218.

Functions of self‐adjoint operators in ideals of compact operators [PDF]
Journal of the London Mathematical Society, 2015 For self‐adjoint operators A,B , a bounded operator J , and a function f:R→C , we obtain bounds in quasi‐normed ideals of compact operators for the difference f(A)J−Jf(B) in terms of the operator AJ−JB .

Compact Operators via the Berezin Transform [PDF]
, 1998 In this paper we prove that if S equals a finite sum of finite products of Toeplitz operators on the Bergman space of the unit disk, then S is compact if and only if the Berezin transform of S equals 0 on the boundary of the disk. This result is new even

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

On Power Compact Operators [PDF]
Proceedings of the American Mathematical Society, 1980 We give an operator theoretic proof of the following result of D. G. Tacon: Theorem. If { T n } \{ {T_n}\} is a sequence of bounded linear operators in a complex infinite dimensional Hilbert space with the property that for every bounded sequence {

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 ...

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).
