Description of Bloch spaces, weighted Bergman spaces and invariant subspaces, and related questions

Kuwait Journal of Science, 2016
Let D be the unit disc of complex plane C, and H=Hol(D) the class of functions analytic in D. Recall that an f∈Hol(D) is said to belong to the Bloch space B=B(D) if ‖f‖_{B}:=sup_{z∈D}(1-|z|²)|f′(z)|

Enhancement of inductance along metallic mesh wires in three-dimensional quasi-isotropic metamaterials using high-ε dielectric particles for impedance-matching with free space

EPJ Applied Metamaterials, 2019
In this paper, we consider cube-shaped unit cells including high-ε dielectric cubes under magnetic dipole-like resonance placed at the center and metallic mesh wires for negative permittivity to construct three-dimensional quasi-isotropic metamaterials ...

Composition Operator, Boundedness, Compactness, Hyperbolic Bloch-Type Space βμ∗, Hyperbolic-Type Space

Journal of Function Spaces, 2020
In this paper, we obtain some characterizations of composition operators Cφ, which are induced by an analytic self-map φ of the unit disk Δ, from hyperbolic Bloch type space βμ∗ into hyperbolic type space QK,p,q∗.

Bounded functions in the little Bloch space [PDF]

Pacific Journal of Mathematics, 1990
The author characterizes the bounded functions in the little Bloch space in terms of the measures arising from the canonical factorization theorem. In particular, this answers a question of D. Sarason by characterizing the Blaschke products in the little Bloch space in terms of the distribution of their zeros.

Products of Composition Operators and Volterra-type Integral Operators from Logarithmic Bloch Spaces into Bloch-type Spaces

, 2012
[[abstract]]Let ' be an analytic self-map of the unit disk D, H(D) the space of analytic functions on D and g 2 H(D). The boundedness and compact- ness of the products of composition operators and Volterra-type integral operators from the logarithmic ...
