A survey on the Campana-Peternell Conjecture

In 1991 Campana and Petemell proposed, as a natural algebro-geometric extension of Mori’s characterization of the projective space, the problem of classifying the complex projective Fano manifolds whose tangent bundle is nef, conjecturing that the only varieties satisfy ing these properties are rational homogeneous. In this paper we review some background material related to this problem, with special attention to the partial results recently obtained by the authors
