Commutators on Weighted Morrey Spaces on Spaces of Homogeneous Type
Analysis and Geometry in Metric Spaces, 2020 In this paper, we study the boundedness and compactness of the commutator of Calderón– Zygmund operators T on spaces of homogeneous type (X, d, µ) in the sense of Coifman and Weiss.

Hadamard Multipliers on Weighted Dirichlet Spaces [PDF]
Integral equations and operator theory, 2019 The Hadamard product of two power series is obtained by multiplying them coefficientwise. In this paper we characterize those power series that act as Hadamard multipliers on all weighted Dirichlet spaces on the disk with superharmonic weights, and we ...

Abstract and Applied Analysis, 2011 Let ψ be a holomorphic mapping on the upper half-plane Π+={z∈ℂ:Jz>0} and φ be a holomorphic self-map of Π+. We characterize bounded weighted composition operators acting from the weighted Bergman space to the weighted-type space on the upper half-plane ...

On the Approximation by Balázs–Szabados Operators
Mathematics, 2021 We present three new approximation properties of the Balázs–Szabados operators. Firstly, we prove that, in certain cases, these operators approximate some super-exponential functions on compact intervals.

Computing heights on weighted projective spaces
, 2018 In this note we extend the concept height on projective spaces to that of weighted height on weighted projective spaces and show how such a height can be computed.

The weighted composition operators on the large weighted Bergman spaces
, 2018 In this paper, we characterize bounded, compact or Schatten class weighted composition operators acting on Bergman spaces with the exponential type weights. Moreover, we give the proof of the necessary part for the boundedness of composition operators on

On persistence properties in fractional weighted spaces [PDF]
, 2014 In this work we derive a point-wise formula that will allows us to study the well-posedness of initial value problem associated to nonlinear dispersive equations in fractional weighted Sobolev spaces $H^s(\R)\cap L^2(|x|^{2r}dx)$, $s, r \in \R$.

Uniqueness of degenerating solutions to a diffusion-precipitation model for clogging porous media
Mathematical Modelling and Analysis, 2022 The current article presents a degenerating diffusion-precipitation model including vanishing porosity and focuses primarily on uniqueness results. This is accomplished by assuming sufficient conditions under which the uniqueness of weak solutions can ...

Hertz potentials and asymptotic properties of massless fields
, 2014 In this paper we analyze Hertz potentials for free massless spin-s fields on the Minkowski spacetime, with data in weighted Sobolev spaces. We prove existence and pointwise estimates for the Hertz potentials using a weighted estimate for the wave ...
