On the Local Picard Group
H. A. Hamm Mathematisches Institut, Westfälische Wilhelms-Universität Münster, Münster, Germany
Abstract:
In his book SGA 2, A. Grothendieck developed Lefschetz theorems for the Picard group, the aim being to compare the Picard group of a projective variety with the one of a hyperplane section. An intermediate object is the Picard group of the formal completion along the hyperplane section. Here we proceed similarly but in the local complex analytic context. The use of the exponential sequence leads to analytic as well as topological depth conditions.
