Enveloppes inferieures de fonctions admissibles sur l'espace projectif complexe. Cas dissymetrique

Abstract

This paper generalizes the first author's preceding works concerning admissible functions on certain Fano manifolds. Here, we study a larger class of functions which can be less symmetric than the ones studied before. When the sup of these functions is null, we prove that they admit a lower bound, giving precisely Tian invariant on these manifolds.
