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 ...

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

On a conjecture of Král concerning the subharmonic extension of continuously differentiable functions [PDF]
Mathematica Bohemica, 2020 This note verifies a conjecture of Král, that a continuously differentiable function, which is subharmonic outside its critical set, is subharmonic everywhere.

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

Separately subharmonic functions need not be subharmonic [PDF]
Proceedings of the American Mathematical Society, 1988 We give an example of a separately subharmonic function which is not subharmonic.

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.

Convex Sets and Subharmonicity of the Inverse Norm Function
Abstract and Applied Analysis, 2022 In this paper, we show that in order for a proper compact subset K of plane ℝ2 to be convex, it is necessary and sufficient that inverse norm function be subharmonic.

Asymptotics of $\delta$-subharmonic functions of finite order
Математичні Студії, 2020 For $\delta$-subharmonic in $\mathbb{R}^m$, $m\geq2$, function $u=u_1-u_2$ of finite positive order we found the asymptotical representation of the form \[ u(x)=-I(x,u_1)+I(x,u_2) +O\left(V(|x|)\right),\ x\to\infty, \] where $I(x,u_i)=\int\limits_{|a-x ...
