Commuting Separately Quasihomogeneous Small Hankel Operators on Pluriharmonic Bergman Space

open access: yesJournal of Function Spaces, 2018
We study (semi)commutativity of small Hankel operators with separately quasihomogeneous symbols on the pluriharmonic Bergman space of the unit ball. Some product problems are also concerned.

Outer‐Sphere Tuning of Synthetic Iron–Sulfur Clusters Within Nanoscale Cage Frameworks

open access: yesSmall, EarlyView.
Noncovalent encapsulation of a synthetic iron–sulfur cluster within hydrophobic, naphthalenediimide (NDI)‐paneled cages is shown to lead to dramatic changes in the electronic structure and covalency of the Fe─S core. ABSTRACT As atomic‐scale archetypes for multi‐electron transfer, iron–sulfur clusters are compelling candidates for the design of redox ...

Bloch-type space of temperature functions on a finite cylinder

open access: yesJournal of Function Spaces and Applications, 2007
We define the Bloch-type space BT as the linear space of temperature functions on the cylinder ST=𝕊1×(0,T) such that sup⁡(x,t)∈T⁡t|∂u∂t(x,t)|

Monitoring GPS‐collared moose by ground versus drone approaches: efficiency and disturbance effects

open access: yesWildlife Biology, EarlyView.
Efficient wildlife management requires precise monitoring methods, for example to estimate population density, reproductive success, and survival. Here, we compared the efficiency of drone (equipped with a RGB camera) and ground approaches to detect and observe GPS‐collared female moose Alces alces and their calves. We also quantified how drone (n = 42)

Composition Operators from the Weighted Bergman Space to the 𝑛th Weighted Spaces on the Unit Disc

open access: yesDiscrete Dynamics in Nature and Society, 2009
The boundedness of the composition operator from the weighted Bergman space to the recently introduced by the author, the 𝑛th weighted space on the unit disc, is characterized.

Reproducing Kernels of Weight Square-Summable Sequences Hilbert Spaces

open access: yesAnnales Mathematicae Silesianae, 2019
In this paper we will introduce the concept of weighted reproducing kernel of l2(ℂ) space, in similiar way as it is done in case of weighted reproducing kernel of Bergman space.

Remarks on hyponormal Toeplitz operators with nonharmonic symbols

open access: yesOpen Mathematics, 2023
In this article, we present some necessary or sufficient conditions for the hyponormality of Toeplitz operator Tφ{T}_{\varphi } on the Bergman space A2(D){A}^{2}\left({\mathbb{D}}).

Interpolating sequences for the Bergman space. [PDF]

open access: yesMichigan Mathematical Journal, 1994
The main results of the paper. Theorem A. Suppose \(A = \{a_ n\}\) is a sequence of interpolation for \(L^ 2_ a (\mathbb{D})\) -- the Bergman Space. Then there exists a unique sequence \(\{t_ n\}\) in \(L^ 2_ a (\mathbb{D})\) such that the kernel function \(K_ A (z,w)\) admits the following partial fraction expansion \[ K_ A (z,w) = (1-z \overline w)^{-

A high‐altitude thermal infrared method for estimating moose abundance and demography in Rocky Mountain National Park, USA

open access: yesWildlife Biology, EarlyView.
Resource managers require accurate estimates of large herbivore abundance and demography to maintain ecological integrity. Common methods to count these species, including observations from low altitude helicopter flights, may conflict with other protected area management objectives and struggle to produce precise estimates for more cryptic species. To

Compact Operators on the Bergman Spaces with Variable Exponents on the Unit Disc of C

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2018
We study the compactness of some classes of bounded operators on the Bergman space with variable exponent. We show that via extrapolation, some results on boundedness of the Toeplitz operators with general L1 symbols and compactness of bounded operators ...
