Jk < Qo Consequently J ~ Q, s<strong>in</strong>ce Q is prime. Thus<br />
I ~ Q, which contradicts the selection of Q. Therefore<br />
P satisfies the right second layer condition.<br />
Corollary 4.36.<br />
Let P be a height 1 prime ideal of a GUFR such<br />
that {p} is right stable. Then P is classically right<br />
localisableo<br />
Proof:<br />
This is an immediate c ons equen c e of theorem 4.14<br />
and theorem 4035.<br />
A semiprime ideal S of a Noetherian r<strong>in</strong>g is said<br />
to be classically right localisable if the f<strong>in</strong>ite set<br />
of prime ideals associated with S<br />
is classically right<br />
localisable. Thus we get another consequence of theorenl<br />
4.35 and theorem 4.23.<br />
Corollary 4.37.<br />
Let S be a semiprime ideal <strong>in</strong> a GUFR and assume<br />
that the associated prime ideals of S are height 1<br />
prime ideals.<br />
Suppose also that the collection of<br />
associated primes is right stable.<br />
Then S is classically<br />
