Fractional differentiation composition operators from Sp spaces to Hq spaces [PDF]
Mathematica MoravicaLet Sp be the space of functions analytic on the unit disk and whose derivatives belong to the Hardy space. In this article, we investigate the boundedness and compactness of the fractional differentiation composition operators from Sp spaces into Hardy ...

Weighted composition operators on Hardy–Smirnov spaces
Concrete Operators, 2022 Operators of type f → ψf ◦ φ acting on function spaces are called weighted composition operators. If the weight function ψ is the constant function 1, then they are called composition operators.

BMO-Boundedness of Maximal Operators and g-Functions Associated with Laguerre Expansions
Journal of Function Spaces and Applications, 2012 Let {𝜑𝛼𝑛}𝑛∈ℕ be the Laguerre functions of Hermite type with index 𝛼. These are eigenfunctions of the Laguerre differential operator 𝐿𝛼=1/2(−𝑑2/𝑑𝑦2+𝑦2+1/𝑦2(𝛼2−1/4)). In this paper, we investigate the boundedness of the Hardy-Littlewood maximal function,

Contractive multipliers from Hardy space to weighted Hardy space [PDF]
, 2012 It is shown how any contractive multiplier from the Hardy space to a weighted Hardy space $H^{2}_{\bbeta}$ can be factored as a fixed factor composed with the classical Schur multiplier (contractive multiplier between Hardy spaces). The result is applied

UMD-valued square functions associated with Bessel operators in Hardy and BMO spaces
, 2013 We consider Banach valued Hardy and BMO spaces in the Bessel setting. Square functions associated with Poisson semigroups for Bessel operators are defined by using fractional derivatives.

Inner functions with derivatives in the weak Hardy space [PDF]
, 2012 It is proved that exponential Blaschke products are the inner functions whose derivative is in the weak Hardy space. As a consequence, it is shown that exponential Blaschke products are Frostman shift invariant.

Advanced Functional Materials, EarlyView.The self‐healable ratiometric mechano‐fluorescent polyurethane (PU) organogel is constructed by incorporating a minor amount (ca. 1.5 wt.%) of the unconventional daisy chain rotaxane (as an artificial molecular muscle toughener) with specific sliding motions and ratiometric emission behaviors into the PU skeleton, which reveals the progressed intrinsic

Angewandte Chemie, EarlyView.Symmetric bis(flourosulfonyl)imide anions in imidazolium‐based ionic liquids direct the formation of a conformal SEI on 3D a‐Si architecture, featuring an ionorganic‐rich (LiF/LiOH) inner and Li2SO4/polymeric outer layer. This anion‐derived, mechanically robust SEI suppresses pulverization and delivers a high reversible capacity of 2489 mAh g−1 at 1C ...

The Hardy space H1 on non-homogeneous metric spaces [PDF]
Mathematical Proceedings of the Cambridge Philosophical Society, 2010 Let (, d, μ) be a metric measure space and satisfy the so-called upper doubling condition and the geometrical doubling condition. We introduce the atomic Hardy space H1(μ) and prove that its dual space is the known space RBMO(μ) in this context.

Gradients of Aliveness and Engineering: A Taxonomy of Fungal Engineered Living Materials
Advanced Materials, EarlyView.This paper explores the potential of fungal engineered living materials (ELMs), examining fungal biology and growth mechanisms, which underpin their development. It presents a classification framework based on aliveness, scaffold composition, and engineering degree. Unique properties such as self‐healing, biosensing, and bioremediation are highlighted,
