Let (R, m) be a commutative Noetherian local ring with infinite residue field R/in. If a is an ideal of R, we will write rad (a) for the radical of a; that is, rad (a) is the intersection of the prime ideals of R which contain a. The arithmetical rank of a, written ara (a), is the smallest integer s such that there exist elements a,,..‘, a, E a with rad (a)= rad ((al,..., a,) R).
