Le but de ce papier est une caractérisation de certaines singularités en fonction d’un nouvel invariant, la “discrépance de Mather”. Nous montrons également quelques résultats nous prouvant que la discrépance de Mather est un invariant raisonnable d’un point de vue de la géométrie birationnelle.

A goal of this paper is a characterization of singularities according to a new invariant, Mather discrepancy. We also show some evidences convincing us that Mather discrepancy is a reasonable invariant in a view point of birational geometry.
