Lefschetz type theorems for algebraic cycles and vector bundles

Sponsor(s): Mathematics
The Weak Lefschetz theorem (or the Lefschetz hyperplane theorem) states that for a smooth, projective variety Y and a smooth hyperplane section X in Y, the restriction map of cohomologies H^i(Y) to H^i(X) is an isomorphism for i
