Entanglement produced by pairs of superposed two-mode coherent and subharmonic cavity light beams [PDF]

Scientific Reports
We examined a two-mode coherent and subharmonic light beam within a cavity that is coupled to a two-mode vacuum reservoir through a single port mirror. Utilizing the solutions of the quantum Langevin equations, we developed Q-functions for the two-mode ...

Harmonic morphisms and subharmonic functions [PDF]

International Journal of Mathematics and Mathematical Sciences, 2005
Let M be a complete Riemannian manifold and N a complete noncompact Riemannian manifold. Let ϕ:M→N be a surjective harmonic morphism. We prove that if N admits a subharmonic function with finite Dirichlet integral which is not harmonic, and ϕ has finite

Multimodal Resonances of a Rectangular Planar Dielectric Elastomer Actuator and Its Application in a Robot with Soft Bristles [PDF]

Biomimetics
Inspired by the fact that flying insects improve their power conversion efficiency through resonance, many soft robots driven by dielectric elastomer actuators (DEAs) have achieved optimal performance via first-order modal resonance.

α-Subharmonic Functions

Современная математика: Фундаментальные направления, 2021
In this paper, we study the class of α-subharmonic functions. A number of important properties of α-subharmonic functions are proved, and an equivalent, more convenient definition of α-subharmonicity is given.

Subharmonic functions in scattering theory

Comptes Rendus. Mathématique, 2021
We present a method that uses the properties of subharmonic functions to control spatial asymptotics of Green’s kernel of multidimensional Schrödinger operator with rough potential.

Subharmonic envelopes for functions on domains

Вестник Самарского университета: Естественнонаучная серия, 2023
One of the most common problems in various fields of real and complex analysis is the questions of the existence and construction for a given function of an envelope from below or from above of a function from a special class H. We consider a case when H

Quasi-Nearly Subharmonicity and Separately Quasi-Nearly Subharmonic Functions

Journal of Inequalities and Applications, 2008
Wiegerinck has shown that a separately subharmonic function need not be subharmonic. Improving previous results of Lelong, Avanissian, Arsove, and of us, Armitage and Gardiner gave an almost sharp integrability condition which ensures a separately ...

ON ENTIRE FUNCTIONS WITH GIVEN ASYMPTOTIC BEHAVIOR

Проблемы анализа, 2018
We study approximation of subharmonic functions on the complex plane by logarithms of moduli of entire functions. In the theory of series of exponentials these entire functions are the main tool.

Fejér-Type Inequalities for Some Classes of Differentiable Functions

Mathematics, 2023
We let υ be a convex function on an interval [ι1,ι2]⊂R. If ζ∈C([ι1,ι2]), ζ≥0 and ζ is symmetric with respect to ι1+ι22, then υ12∑j=12ιj∫ι1ι2ζ(s)ds≤∫ι1ι2υ(s)ζ(s)ds≤12∑j=12υ(ιj)∫ι1ι2ζ(s)ds.
