Universality on higher order Hardy spaces [PDF]

, 2005
We prove a Seidel-Walsh-type theorem about universality of a sequence of derivation-composition operators generated by automorphisms of the unit disk in the setting of the higher order Hardy spaces.

Weighted composition operators on bicomplex Lorentz spaces with their characterization and properties

Demonstratio Mathematica
This article presents a characterization of non-singular measurable transformation, denoted as TT, mapping from Ω\Omega to itself, along with bicomplex-valued BC{\mathbb{BC}}-measurable function uu defined on Ω\Omega , which induces a weighted ...

Complex symmetric weighted composition Lambert type operators on L^2(Σ)

, 2018
In this paper we obtain the polar decomposition and the Aluthge transform of a weighted composition Lambert type operator MwEMuCφ on L2(Σ) . In addition, we study the complex symmetry of these types of operators induced by triple (w,u,φ) .

On the commutativity of Toeplitz operators with harmonic symbols

, 2018
In this paper we prove that if the polar decomposition of a symbol f is truncated above, i.e., f (reiθ ) = ∑k=−∞ e ikθ fk(r) where the fk ’s are radial functions, and if the associated Toeplitz operator Tf commutes with Tz2+ z2 , then Tf = Q(Tz2+ z2 ...

Relations between two classes of real functions and applications to boundedness and compactness of operators between analytic function spaces

, 2016
Some relations between two classes of real functions, the class of positive lower type p , denoted by Lp , and the class of positive upper type q , denoted by Uq , which naturally appear in the definition of some Hardy-Orlicz and Bergman-Orlicz type ...

Some Hardy's inequalities on conformable fractional calculus

Demonstratio Mathematica
In this article, we will demonstrate some Hardy’s inequalities by utilizing Hölder inequality, integration by parts, and chain rule of the conformable fractional calculus.
