Maps between local Picard groups

Research output: Contribution to journalArticle

Abstract

The paper investigates maps between local Picard groups. The main goal is to understand the kernel in two cases: pull-back to the normalization and restriction to a hyperplane section. We give suffcient (and almost necessary) conditions that guarantee that the kernel is finite or of finite type.
