Operators commuting with complex symmetric weighted composition operators on H 2
In this article, we initially study when an anti-linear Toeplitz operator is in the commutant of a composition operator. Primarily, we investigate weighted composition operators Wg,ψ{W}_{g,\psi } commuting with complex symmetric weighted composition ...

Weighted composition operators [PDF]
This thesis contains some results on weighted composition operators on weighted Hardy spaces of the open unit disk D of the complex plane. If ψ is an analytic map on the open unit disk and ϕ an analytic map from the open unit disk into itself, the ...

Unbounded weighted composition operators in $L^{2}$-spaces [PDF]
This book establishes the foundations of the theory of bounded and unbounded weighted composition operators in L²-spaces. It develops the theory in full generality, meaning that the weighted composition operators under consideration are not regarded as ...

An unexpected alternative interaction site for ethyl viologen was identified in formate dehydrogenase 1 from Methylorubrum extorquens. Combined mutagenesis, kinetic analysis, and docking revealed that aromatic residues near an iron–sulfur cluster enable flavin mononucleotide‐independent electron transfer, offering a framework for engineering improved ...

Binormal Weighted Composition Operators on the Fock Space
The aim of this paper is to obtain the sufficient and necessary conditions for weighted composition operators uCφ with φz=az+b a≤1, uz=ced¯z, where a,b,c,d∈ℂ, to be binormal or quasinormal on the Fock space F2. Surprisingly, the normality, quasinormality,

Compact and Fredholm weighted composition operators [PDF]
The study of weighted composition operators on various function spaces has received considerable attention in past decades. Characterizations, which usually involve interplay of symbol functions, for certain types of weighted composition operators have ...

The physical dimensions and shape of bacterial cells define the surface area available to acquire nutrients and the volume available for synthesizing proteins and DNA. Here, we use computational systems biology to decode the importance of cell geometry as a major determinant of prokaryotic phenotype, including growth rate and metabolic efficiency. This

On the stability index for weighted composition operators
An operator \(S:C(X)\to C(Y)\) is said to be a weighted composition operator (denoted \(S\in \mathbf {WCM}(X,Y)\)) if there exists \(a\in C(Y)\) and a map \(h:Y\to X\), continuous on \(\{y\in Y: a(y)\not=0\}\), such that \((Sf)(y)= a(y) f(h(y))\) for every \(f\in C(X)\) and \(y\in Y\). For \(\varepsilon\geq0\), the linear operator \(T:C(X)\to C(Y)\) is
