Cohomologie locale des faisceaux cohérents et théorèmes de Lefschetz locaux et globaux (SGA 2)
Alexander Grothendieck, Michele Raynaud
Abstract
New updated edition by Yves Laszlo of the book ``Cohomologie locale des faisceaux cohérents et théorèmes de Lefschetz locaux et globaux (SGA 2)'', Advanced Studies in Pure Mathematics 2, North-Holland Publishing Company - Amsterdam, 1968. Published by the Societe Mathematique de France http://smf.emath.fr/Publications/DocumentsMathematiques/ Original text also available in the LaTeX file. Dans cet ouvrage, on montre des théorèmes d'algébrisation et de pureté qui permettent d'obtenir des théorèmes de type Lefschetz pour le groupe fondamental ou de Picard. In this monograph algebraization and purity theorems are proved, providing Lefschetz's theorem for both the fundamental group and the Picard group.
