Abstract
Let S_k be the class of complex algebraic k-folds X \subset P^n such that H_i(X,Q) \cong H_i(H,Q) for i \leq k-1, H being a general hyperplane section. Topological characterizations of S_k and several other classes of projective manifolds are given. Moreover, classes S_2, S_3, S_5 are completely described and a partial description of S_4 is given. A key role is played by projective bundles.
