The Bohr Radius of the Weighted Bloch Spaces
Lobachevskii Journal of Mathematics, 2023 The concept of the Bohr radius of a pair of Banach spaces is introduced. The lower estimate for the value of the Bohr radius from the Bloch space to the space of bounded functions obtained by I. Kayumov, S. Ponnusamy and N. Shakirov is slightly improved. It is shown that for any weighted Bloch space the Bohr radius is not less than $1/\sqrt{2}$.

Emergent 3D Fermiology and Magnetism in an Intercalated Van der Waals System
Advanced Science, EarlyView.An emergent three‐dimensional electronic state is uncovered in an intercalated van der Waals system. A spin‐polarized intercalant‐host hybridized band crossing the Fermi level provides an itinerant channel for interlayer exchange, highlighting how electronic dispersion governs magnetic dimensionality.

On an Integral-Type Operator Acting between Bloch-Type Spaces on the Unit Ball
Abstract and Applied Analysis, 2010 Let 𝔹 denote the open unit ball of ℂn. For a holomorphic self-map φ of 𝔹 and a holomorphic function g in 𝔹 with g(0)=0, we define the following integral-type operator: Iφgf(z)=∫01ℜf(φ(tz))g(tz)(dt/t), z∈𝔹.

Gap‐Free Information Transfer in 4D‐STEM via Fusion of Complementary Scattering Channels
Advanced Science, EarlyView.Fused Full‐Field STEM (FF‐STEM) is introduced as a 4D‐STEM imaging modality that combines direct ptychography with tilt‐corrected dark‐field reconstruction in a single acquisition. Fourier‐space fusion using Wiener‐type spectral weighting closes the low‐frequency contrast gap inherent to bright‐field methods, delivering gap‐free, dose‐efficient, near ...

Composition Operators Mapping Logarithmic Bloch Functions into Hardy Space
Journal of Function Spaces, 2018 Characterizing the hyperbolic Hardy classes, several g-functions of hyperbolic type are introduced. Using this, necessary and sufficient conditions on the inducing self-maps are established for the boundedness of the composition operators from ...

The composition operators on weighted Bloch space [PDF]
Archiv der Mathematik, 2002 Let \(H(D)\) denote the set of all holomorphic functions in the open unit disk \(D\) and let \(\phi\) be a holomorphic selfmap of \(D\). Suppose that \(X\) and \(Y\) are two function spaces defined on \(D\). The map \(\phi\) is said to have the \(X\)-to-\(Y\) pullback property if \(f\circ \phi\in Y\) for every \(f\in X\).
