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.

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 ...

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

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.

Bifurcation curves of subharmonic solutions
, 2019 We revisit a problem considered by Chow and Hale on the existence of subharmonic solutions for perturbed systems. In the analytic setting, under more general (weaker) conditions, we prove their results on the existence of bifurcation curves from the ...

Representation of subharmonic functions in a half-plane
, 2021 The theory of subharmonic functions of finite order is based to a considerable extent on integral formulae. In the present paper representations are obtained for subharmonic functions in the upper half-plane with more general growth gamma(r) than finite ...
