Resumen de The Dispersing of Geodesics in Berwald Spaces of Non-Positive Flag curvature

László Kozma, Csaba Varga, Alexandru Kristály

• It is proved that a forward complete Berwald space of non-positive flag curvature is a generalized Busemann's geodesic space of non-positive curvature: the length of a median line in any geodesic triangle cannot succeed the half length of the corresponding side.
