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 ...

The shape of higher-dimensional state space: Bloch-ball analog for a qutrit [PDF]

open access: yesQuantum, 2021
Geometric intuition is a crucial tool to obtain deeper insight into many concepts of physics. A paradigmatic example of its power is the Bloch ball, the geometrical representation for the state space of the simplest possible quantum system, a two-level ...

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)|

Classical Wakimoto Realizations of Chiral WZNW Bloch Waves [PDF]

open access: yes, 1999
It is well-known that the chiral WZNW Bloch waves satisfy a quadratic classical exchange algebra which implies the affine Kac-Moody algebra for the corresponding currents.

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.

Bicomplex Bergman and Bloch spaces [PDF]

open access: yesArabian Journal of Mathematics, 2020
AbstractIn this article, we define the bicomplex weighted Bergman spaces on the bidisk and their associated weighted Bergman projections, where the respective Bergman kernels are determined. We study also the bicomplex Bergman projection onto the bicomplex Bloch space.

Weighted Differentiation Composition Operators from the α-Bloch Space to the $\alpha-$Bloch-Orlicz Space [PDF]

open access: yesOperators and Matrices, 2019
Summary: The boundedness and the compactness of the weighted differentiation composition operators from the \(\alpha\)-Bloch space \(\mathscr{B}_\alpha\) to the \(\alpha\)-Bloch-Orlicz space \(\mathscr{B}^\varphi_\alpha\) with \(\alpha > 0\) are investigated respectively in this paper.
