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.

Quasi-Nearly Subharmonicity and Separately Quasi-Nearly Subharmonic Functions [PDF]
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 ...

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

Domination Conditions for Families of Quasinearly Subharmonic Functions
International Journal of Mathematics and Mathematical Sciences, 2011 Domar has given a condition that ensures the existence of the largest subharmonic minorant of a given function. Later Rippon pointed out that a modification of Domar's argument gives in fact a better result.

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 ...

L^p-subharmonic functions in R^n
Electronic Journal of Differential Equations, 2016 We prove that if u is an $L^p$-subharmonic function defined outside a compact set in $\mathbb{R}^n$, it is bounded above near infinity, in particular, if the subharmonic function u is in $L^p(\mathbb{R}^n)$, $1\leq ...

Subharmonic functions and electric fields in ball layers. II [PDF]
Математичні Студії, 2011 In this sequel to cite{GK} we study a special case $BL(frac{1}{r},r)$, $r>1$. Alsothe explicit representation of a subharmonic extension for a subharmonic function $u(x)$ near a removable point is obtained.
