On a class of commutative Noetherian rings

  • Lindsay Burch (a1)


If A, B are ideals of a commutative ring R, such that BA, and, for some positive integer r, Ar = BAr−1 then B is said to be a reduction of A. (This concept was defined and developed by Northcott and Rees in (1).) In this paper, I shall consider commutative Noetherian rings with the property that no non-zero principal ideal is a reduction of an ideal properly containing it.
