( 1) RX- 1 is a right No e th e r i.an r<strong>in</strong>g.<br />
(2) For any ideal I of RX- 1, r C is an ideal of R.<br />
(3) For any id ea.l I of R, .re is an ideal of RX- 1.<br />
(4) For any ideal I of RX- 1 , I = (rc)e.<br />
(5) An idea 1 I of RX- 1 is prime (semiprime) if<br />
and orly if re is prime (semiprime) <strong>in</strong> R.<br />
(6) Let P be a prime (semiprime) ideal of Ro<br />
Then P = QC for some prime (semiprime) ideal<br />
if and only if X ~ C(p).<br />
Proof:<br />
As <strong>in</strong> [19, theorem 9.20].<br />
Remark 2 013.<br />
We look at T, the partial quotient r<strong>in</strong>g of R at c.<br />
S<strong>in</strong>ce C S C R<br />
(0),. it is obvious that T ~ Q(R), the Art<strong>in</strong>ian<br />
quotient r<strong>in</strong>g ofR formed by localis<strong>in</strong>g R at CR(O)o<br />
Now<br />
T has the follow<strong>in</strong>g properties.<br />
Theorem 2.15.<br />
Let R be a GUFR and T be the partial quotient r<strong>in</strong>g<br />
of Rat Co<br />
Then<br />
(1) T is a GUFR<br />
(2) T has an Art<strong>in</strong>ian quotient r<strong>in</strong>g<br />
(3) C(T) = '[t
