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.

Hatching and fledging? A meta‐analysis of the performance effects of business incubators

open access: yesStrategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Business incubators are among the most widely implemented instruments to foster entrepreneurship. Yet empirical evidence on their effectiveness remains fragmented and often contradictory. Limited research systematically compares how different types of incubators influence multiple venture performance outcomes, including ...

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)|

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.

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 ...

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.

Creating a Masterpiece. The Road to (and Beyond) Woodward and Hoffmann's 1969 Angewandte Chemie Treatise

open access: yesThe Chemical Record, EarlyView.
This publication describes how R. B. Woodward and Roald Hoffmann crafted their masterpiece publications. Illustrations include Woodward's first draft of the famous “Violations There are none. Nor can violations be expected of so fundamental a principle of maximum bonding.” Original but discarded text shows the stepwise paths toward the W‐H masterpieces.

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 ...

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)

Finite rank intermediate Hankel operators on the Bergman space [PDF]

open access: yesSurveys in Mathematics and its Applications, 2011
In this paper we characterize the kernel of an intermediate Hankel operator on the Bergman space in terms of the inner divisors and obtain a characterization for finite rank intermediate Hankel operators.
