Abstract
This paper centers around Artinianness of the local cohomology of -modules. Let be an ideal of a commutative Noetherian ring . The notion of -relative Goldie dimension of an -module , as a generalization of that of Goldie dimension is presented. Let be a -module such that -relative Goldie dimension of any quotient of is finite. It is shown that if , then the local cohomology modules are Artinian. Also, it is proved that if is finite, then is Artinian, for any ideal of . These results extend the previously known results concerning Artinianness of local cohomology of finitely generated modules.
