Toeplitz-Superposition Operators on Analytic Bloch Spaces [PDF]
The important purpose of this current work is to study a new class of operators, the so-called Toeplitz-superposition operators as an expansion of the weighted known composition operators, induced by such continuous entire functions mapping on bounded specific sets.

Continuity properties of the superposition operator [PDF]
AbstractVarious continuity conditions (in norm, in measure, weakly etc.) for the nonlinear superposition operatorF x(s) =f(s, x(s)) between spaces of measurable functions are established in terms of the generating functionf = f(s, u). In particular, a simple proof is given for the fact that, ifFis continuous in measure, thenfmay be replaced by a ...

Coherent and incoherent superposition of transition matrix elements of the squeezing operator
We discuss the general matrix elements of the squeezing operator between number eigenstates of a harmonic oscillator (which may also represent a quantized mode of the electromagnetic radiation).

On Generalized Step-Functions and Superposition Operators [PDF]
Abstract For a given σ-ideal of sets, the notion of a generalized stepfunction is introduced and investigated in connection with the problem of sup-measurability of certain functions of two variables, regarded as superposition operators.

Analytic Morrey Spaces and Bloch-Type Spaces
This paper is devoted to characterizing the boundedness of the Riemann-Stieltjes operators from analytic Morrey spaces to Bloch-type spaces. Moreover, the boundedness of the superposition operator and weighted composition operator on analytic Morrey ...

Bounds on positive operator-valued measure based coherence of superposition
Quantum coherence is a fundamental feature of quantum physics and plays a significant role in quantum information processing. By generalizing the resource theory of coherence from von Neumann measurements to positive operator-valued measures (POVMs ...
