Let I be an ideal in a polynomial ring over a perfect field. We give new methods for comput ing the equidimensional parts and radical of I, for localizing I with respect to another ideal, and thus for finding the pr imary decomposit ion of / . Our methods rest on modern ideas from commutat ive algebra, and are direct in the sense that they avoid the generic projections used by Hermann (1926) an...
for the first time nakayama introduced qf-ring. in 1967 carl. faith and elbert a. walker showed that r is qf-ring if and only if each injective right r-module is projective if and only if each injective left r-modules is projective. in 1987 s.k.jain and s.r.lopez-permouth proved that every ring homomorphic images of r has the property that each cyclic s-module is essentialy embeddable in dire...
