Abstract:
Noether–Lefschetz Theorem states that a sufficiently general surface
of a 3-dimensional complex projective space has $Z$ as its Picard group.
Griffiths and Harris gave a more algebraic proof of this fact than the
one proposed by Lefschetz. It uses a construction of a family of
surfaces that degenerates to a reducible surface, and a computation of
a Picard group of this reducible fiber.
