On the axiomatic of harmonic functions II
Annales de l'Institut Fourier, Volume 13 (1963) no. 2, p. 389-394
On démontre dans l’axiomatique de M. Brelot la linéarité de l’opération de balayage appliquée aux fonctions surharmoniques en utilisant seulement les axiomes 1, 2, 3, l’espace de base n’ayant pas nécessairement une base dénombrable.
