Inequalities involving norm and essential norm of weighted composition operators [PDF]
Journal of Mathematical Inequalities, 2017 Summary: We characterize the boundedness and compactness of the weighted composition operator acting from the weighted Bergman space \(\mathcal{A}^p(\sigma)\) to the Zygmund-type space \(\mathcal{Z}_\nu\), where \(\sigma\) is an admissible weight and \(\nu\) is a normal weight. Some upper and lower bounds for the norm and essential norm of the operator

Norms of a Product of Integral and Composition Operators between Some Bloch-Type Spaces
Axioms, 2023 We present some formulas for the norm, as well as the essential norm, of a product of composition and an integral operator between some Bloch-type spaces of analytic functions on the unit ball, in terms of given symbols and weights.

Essential norm of an integral-type operator from ω-Bloch spaces to μ-Zygmund spaces on the unit ball [PDF]
Opuscula Mathematica, 2018 In this paper, we give an estimate for the essential norm of an integral-type operator from \(\omega\)-Bloch spaces to \(\mu\)-Zygmund spaces on the unit ball.

ESSENTIAL NORM OF THE PULL BACK OPERATOR
Korean Journal of Mathematics, 2016 Summary: We obtain some estimations of the essential norm of a pull back operator induced by quasi-symmetric homeomorphisms. As a corollary, we deduce the compactness criterion of this operator.

Essential norm of composition operators on Harmonic Bloch spaces
Filomat, 2022 In this paper we characterize essential norm of composition operators on the spaces of Harmonic Bloch functions. We obtain some upper and lower bounds for the essential norm of composition operators between Harmonic Bloch function spaces. In some cases we find exact value of the essential norm such as in Theorems 2.7 and 2.11. These results

Super Poincaré Inequalities, Orlicz Norms and Essential Spectrum [PDF]
Potential Analysis, 2010 We prove some results about the super Poincar inequality (SPI) and its relation to the spectrum of an operator: we show that it can be alternatively written with Orlicz norms instead of L1 norms, and we use this to give an alternative proof that a bound on the bottom of the essential spectrum implies a SPI.

Norm and Essential Norm of a Weighted Composition Operator on the Bloch Space [PDF]
Integral Equations and Operator Theory, 2017 We give some new estimates for the norm and essential norm of a weighted composition operator on the Bloch space. As corollaries, we obtain some new characterizations of the boundedness and compactness of a weighted composition operator on the Bloch space.

Essential norm of the differential operator [PDF]
Operators and Matrices, 2019 This paper is a follow-up contribution to our work [10] where we studied some spectral properties of the differential operator $D$ acting between generalized Fock spaces $\mathcal{F}_{(m,p)}$ and $\mathcal{F}_{(m,q)}$ when both exponents $p$ and $q$ are finite.

MathematicsIn this work, we characterize the boundedness of t-generalized composition operators from F(p, q, s) spaces to iterated weighted-type Banach space. We also provide estimates of the norm and the essential norm of t-generalized composition operators from F(
