Integral type operators from normal weighted Bloch spaces to QT,S spaces

open access: yesJournal 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.

Norm and Essential Norm of Composition Followed by Differentiation from Logarithmic Bloch Spaces to Hμ∞

open access: yesAbstract 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 ...

On α-Bloch Spaces and Multipliers of Dirichlet Spaces

open access: yesJournal of Mathematical Analysis and Applications, 1997
Suppose \(B^\alpha, \alpha\in (0, \infty); Q_p, p\in (0, \infty)\) and \(D_\alpha, \alpha\in (-\infty, 2)\) are the spaces of all analytic functions \(f\) in the unit disc \(D:| z|

Weighted Composition Operators from Hardy Spaces into Logarithmic Bloch Spaces

open access: yesJournal of Function Spaces and Applications, 2012
The logarithmic Bloch space Blog⁡ is the Banach space of analytic functions on the open unit disk 𝔻 whose elements f satisfy the condition ∥f∥=sup⁡z∈𝔻(1-|z|2)log⁡  (2/(1-|z|2))|f'(z)|

Compact Composition Operators between Bloch Type Spaces in the Polydisk

open access: yesAbstract and Applied Analysis, 2012
Wulan et al. (2009), Wulan et al. characterized the compactness of composition operators on the Bloch space in the unit disk by the th power of the induced analytic function. This paper will generalize the result to the Bloch type space in the polydisk.

Toeplitz Operator and Carleson Measure on Weighted Bloch Spaces

open access: yesJournal of Function Spaces, 2019
In this paper, we consider Toeplitz operator acting on weighted Bloch spaces. Meanwhile, the inclusion map from weighted Bloch spaces into tent space is also investigated.

Phase-space representations of the Bloch equation [PDF]

open access: yesPhysical Review A, 1985
The authors discuss the phase-space representation of the Bloch equation and present analytic expressions for two generalized classes of distribution functions. Series solutions to order of {h bar}{sup 2} are given. The authors conclude that the Wigner quantum corrections are the simplest among the two general classes of distribution functions. 21 refs.

Topological order on the Bloch sphere

open access: yesNew Journal of Physics, 2020
A Bloch sphere is the geometrical representation of an arbitrary two-dimensional Hilbert space. Possible classes of entanglement and separability for the pure and mixed states on the Bloch sphere were suggested by [Boyer et al 2017 PRA 95 032 308].
