ABSTRACT

As in Sections 13 and 14 throughout, let A be an integrally closed noetherian domain. We consider a regular sequence F 0,…,Fn of homogeneous polynomials of positive degrees δ 0,…,δn in the graded polynomial algebra A[T] = A[T 0,…,Tn ] with deg Ti = γ i > 0 and the graded A-algebra C = A[T]/(F 0,…,Fn ).
