POSITIVE HARMONIC FUNCTIONS IN UNIFORM AND ADMISSIBLE DOMAINS

Analysis (Germany), 1988
The authors prove inequalities for a class of functions, including positive harmonic functions, in various types of domain. Their most interesting inequalities involve the distance to the boundary of the domain. For example, for certain domains D (bounded uniform domains) in \(R^ n\) (n\(\geq 2)\) and for any positive harmonic function u in D, we have \

Admissible Functions for the Positive Octant

Mathematical Notes, 2004
In this paper, we give examples of admissible functions for the positive octant, which are multidimensional generalizations of regularly varying functions of a single variable introduced by J. Karamata in 1930. For an arbitrary closed convex acute solid n-dimensional cone, admissible functions were introduced by Yu. N. Drozhzhinov and B. I.

Positive Numberings in Admissible Sets

open access: yesSiberian Mathematical Journal, 2020
© 2020, Pleiades Publishing, Ltd. We construct the example of an admissible set A such that there exists a positive computable A-numbering of the family of all A-c.e.

On Positive Superharmonic Functions in a -Admissible Domains

Journal of the London Mathematical Society, 1984
The author introduces a new boundary property of domains. He calls it a- admissible and proves that if a bounded domain D in \({\mathbb{R}}^ N\), \(N\geq 2\), is a-admissible and if u is a positive superharmonic function in D, then u(x)\(\geq k dist(x,D)\) in D for some positive constant k.
