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.

Against Essential Mental Normativity Again [PDF]
Dialogue, 2011 ABSTRACT: In a recent paper (2008), I presented two arguments against the thesis that intentional states are essentially normative. In this paper, I defend those arguments from two recent responses, one from Nick Zangwill in his (2010) and one from Daniel Laurier in the present volume, and offer improvements of my arguments in light of Laurier’s ...

The essential norm of a weighted composition operator on BMOA [PDF]
Mathematische Zeitschrift, 2014 We provide an estimate for the essential norm of a weighted composition operator $W_{ψ,φ}\colon f\mapsto ψ(f\circφ)$ acting on the space $BMOA$ in terms of the weight function $ψ$ and the $n$-th power $φ^n$ of the analytic self-map $φ$ of the open unit disc $\mathbb{D}$.

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

On essential norm of the Neumann operator [PDF]
Mathematica Bohemica, 1992 The author gives an estimate of the essential norm of the Neumann operator. It is shown that under a deformation of the domain investigated by a diffeomorphism, which is conformal on a precisely specified part of the boundary, for the given norm there exists a norm on the space of continuous functions on the boundary of the deformated domain such that ...

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(
