THE FUNDAMENTAL EXACT SEQUENCE, A NEW PERSPECTIVE
Cornel Baetica
|
Abstract: This paper aims at a new perspective on the fundamental exact sequence of the divisor class groups of Simis and Trung [4] via the divisorial closure of a filtration. We also obtain similar exact (splitting) sequences for the Rees algebras associated to these new filtrations. |
Keywords and phrases: divisor class group, divisorial closure, Rees algebra. |
