If f # L 1 (d+) is harmonic in the space GΓK, where + is a radial measure with +(GΓK)=1, we have, by the mean value property f = f V +. Conversely, does this mean value property imply that f is harmonic ? In this paper we give a new and natural proof of a result obtained by P. Ahern, A. Flores, W. R

β¦ Synopsis
A class of radial measures + on R n is defined so that integrable harmonic functions f on R n may be characterized as solutions of convolution equations f V += f. In particular we show that f V e &2 V ? |x| = f, f # L 1 (e &2? |x| ) is harmonic if and only if n<9.

Let β be a bounded open set in R n , n ΟΎ 2, with R n Οͺ β a connected set that is not thin at each point of Ρ¨β. Then any solution to a Dirichlet problem for given continuous boundary data on Ρ¨β can be approximated in a simple way by a sum that involves one function f (z) of a single complex variable
## Abstract Using Typeβ2 theory of effectivity, we define computability notions on the spaces of Lebesgueβintegrable functions on the real line that are based on two natural approaches to integrability from measure theory. We show that Fourier transform and convolution on these spaces are computabl
## Abstract Let __X__ be a standard Markov process with state space __E__ and let __F__ be a closed subset of __E__. A nonnegative function __f__ on __F__ is extended probabilistically to a function __h~f~__ on the whole space __E__. We show that the extension __h~f~__ is harmonic with respect to _
