dc.descriptionIn this paper we study compact manifolds with 2-nonnegative Ricci operator, assuming that their Weyl operator satisfies certain conditions which generalize conformal flatness. As a consequence, we obtain that such manifolds are either locally symmetric or their Betti numbers between and n-2 vanish. We also study the topology of compact hypersurfaces with 2-nonnegative Ricci operator.
