Weighted Composition Operators from Generalized Weighted Bergman Spaces to Weighted-Type Spaces [PDF]

open access: yesJournal of Inequalities and Applications, 2009
Let φ be a holomorphic self-map and let ψ be a holomorphic function on the unit ball B. The boundedness and compactness of the weighted composition operator ψCφ from the generalized weighted Bergman space into a class of ...

Weighted Calderón-Hardy spaces [PDF]

open access: yesMathematica Bohemica
We present the weighted Calderón-Hardy spaces on Euclidean spaces and investigate their properties. As an application we show, for certain power weights, that the iterated Laplace operator is a bijection from these spaces onto classical weighted Hardy ...

Weighted Sobolev Spaces on Metric Measure Spaces [PDF]

open access: yesJournal für die reine und angewandte Mathematik (Crelles Journal), 2015
We investigate weighted Sobolev spaces on metric measure spaces $(X,d,m)$. Denoting by $\rho$ the weight function, we compare the space $W^{1,p}(X,d,\rho m)$ (which always concides with the closure $H^{1,p}(X,d,\rho m)$ of Lipschitz functions) with the ...

On Weighted Sobolev Spaces [PDF]

open access: bronzeCanadian Journal of Mathematics, 1996
AbstractWe study density and extension problems for weighted Sobolev spaces on bounded (ε, δ) domains𝓓when a doubling weight w satisfies the weighted Poincaré inequality on cubes near the boundary of 𝓓 and when it is in the MuckenhouptApclass locally in 𝓓. Moreover, when the weightswi(x) are of the form dist(x,Mi)αi,αi∈ ℝ,Mi⊂ 𝓓that are doubling, we are

Global universal approximation of functional input maps on weighted spaces [PDF]

open access: yesConstructive approximation, 2023
We introduce so-called functional input neural networks defined on a possibly infinite dimensional weighted space with values also in a possibly infinite dimensional output space.

Extrapolation of compactness on weighted spaces [PDF]

open access: yesRevista matemática iberoamericana, 2020
Let $T$ be a linear operator that, for some $p_1\in(1,\infty)$, is bounded on $L^{p_1}(\tilde w)$ for all $\tilde w\in A_{p_1}(\mathbb R^d)$ and in addition compact on $L^{p_1}(w_1)$ for some $w_1\in A_{p_1}(\mathbb R^d)$. Then $T$ is bounded and compact

On the linearized system of elasticity in the half-space

open access: yesAIMS Mathematics, 2022
The purpose of this paper is twofold. The first goal is to provide a simple and constructive proof of Korn inequalities in half-space with weighted norms. The proof leads to explicit values of the constants.

Convergence of generalized sampling series in weighted spaces

open access: yesDemonstratio Mathematica, 2022
The present paper deals with an extension of approximation properties of generalized sampling series to weighted spaces of functions. A pointwise and uniform convergence theorem for the series is proved for functions belonging to weighted spaces.

Variational characterizations of weighted Hardy spaces and weighted spaces

open access: yesProceedings of the Royal Society of Edinburgh: Section A Mathematics, 2021
This paper obtains new characterizations of weighted Hardy spaces and certain weighted $BMO$ type spaces via the boundedness of variation operators associated with approximate identities and their commutators, respectively.

Norms of some operators between weighted-type spaces and weighted Lebesgue spaces

open access: yesAIMS Mathematics, 2023
We calculate the norms of several concrete operators, mostly of some integral-type ones between weighted-type spaces of continuous functions on several domains.
