Divisor class groups and graded canonical modules of multisection rings
Published online by Cambridge University Press: 11 January 2016
Abstract
We describe the divisor class group and the graded canonical module of the multisection ring T (X;D1,…, Ds) for a normal projective variety X and Weil divisors D1,…, Ds on X under a mild condition. In the proof, we use the theory of Krull domain and the equivariant twisted inverse functor.
