二维格式中的整体瓣环

Rings of global sections in two-dimensional schemes

Holger Brenner

摘要:

本文研究了Spec A中开子集U=D(I)的整体瓣环,其中A是二维诺特环.主要考虑的是给出一个几何判据,当这些环是双生成的,以纠正一个无效的声明Schenzel。

英文摘要:

In this paper we study the ring of global sections of an open subset U=D(I) in Spec A, where A is a two-dimensional noetherian ring. The main concern is to give a geometric criterion when these rings are finitely generated, in order to correct an invalid statement of Schenzel.
