Abstract |
|
Let C(A) denote the class group of a Krull domain A. Samuel has established (a) C(A) → C(A[[X1,⋯,Xn]]) is injective, and (b) C(A) → C(A[[X1,⋯,Xn]]) is bijective in Case A is a regular U.F.D. This note establishes that C(A) → C(A[[X1,⋯,Xn]]) is bijective in Case A is a regular noetherian domain, thus adding a complement to (a) while generalizing (b). A corollary of this is that A[[X1,⋯,Xn]]S is a U.F.D. if A is a regular Noetherian domain and S is the set of nonzero elements of A. |
