Analytic Morrey Spaces and Bloch-Type Spaces [PDF]
Journal of Function Spaces, 2018 This paper is devoted to characterizing the boundedness of the Riemann-Stieltjes operators from analytic Morrey spaces to Bloch-type spaces. Moreover, the boundedness of the superposition operator and weighted composition operator on analytic Morrey spaces is discussed, respectively.

Distance of a Bloch Function to the Little Bloch Space [PDF]
Bulletin of the Australian Mathematical Society, 2006 Motivated by a formula of P. Jones that gives the distance of a Bloch function to BMOA, the space of bounded mean oscillations, we obtain several formulas for the distance of a Bloch function to the little Bloch space, β0. Immediate consequences are equivalent expressions for functions in β0.

Chirped Bloch-harmonic oscillations in a parametrically forced optical lattice
Physical Review Research, 2023 The acceleration theorem for wave packet propagation in periodic potentials disentangles the k-space dynamics and real space dynamics. This is well known and understood for Bloch oscillations and super Bloch oscillations in the presence of position ...

Observation of Magnetic-Anisotropy Crossover and High-Temperature Skyrmions in the Dirac Magnet Fe<sub>3</sub>Ge with a Distorted Kagome Lattice. [PDF]
Adv Sci (Weinh)A temperature‐driven magnetic anisotropy crossover is revealed in the Dirac kagome magnet Fe3Ge with a distorted kagome lattice. The transition from easy‐plane to easy‐axis magnetic anisotropy stabilizes robust Bloch‐type skyrmions over an exceptionally wide temperature window of 375–650 K.

Stiefel-Whitney topological charges in a three-dimensional acoustic nodal-line crystal
Nature Communications, 2023 Band topology of materials describes the extent Bloch wavefunctions are twisted in momentum space. Such descriptions rely on a set of topological invariants, generally referred to as topological charges, which form a characteristic class in the ...

On the Closures of Dirichlet Type Spaces in the Bloch Space
Complex Analysis and Operator Theory, 2017 Let $\mathbb{D}$ be the open unit disk in the complex plane, and let $\mathrm{Hol}(\mathbb{D})$ denote the space of holomorphic functions on the unit disk. A function $f\in\mathrm{Hol}(\mathbb{D})$ is said to belong to the Bloch space $\mathcal{B}$ if \[ \|f\|_{\mathcal{B}}=|f(0)|+\sup_{z\in\mathbf{D}}(1-|z|^2)|f^\prime (z)|-1$, the space $\mathcal{D ...

Distance from Bloch-Type Functions to the Analytic Space F(p,q,s)
Abstract and Applied Analysis, 2014 The analytic space F(p,q,s) can be embedded into a Bloch-type space. We establish a distance formula from Bloch-type functions to F(p,q,s), which generalizes the distance formula from Bloch functions to BMOA by Peter Jones, and to F(p,p-2,s) by Zhao.

Integral type operators from normal weighted Bloch spaces to QT,S spaces
Journal of Hebei University of Science and Technology, 2016 Operator theory is an important research content of the analytic function space theory. The discussion of simultaneous operator and function space is an effective way to study operator and function space.

Abstract and Applied Analysis, 2014 In this note we express the norm of composition followed by differentiation DCφ from the logarithmic Bloch and the little logarithmic Bloch spaces to the weighted space Hμ∞ on the unit disk and give an upper and a lower bound for the essential norm of ...
