  Abstract:
For a finitely generated module M, over a commutative Noetherian local ring (R,\frak m), it is shown that there exist only a finite number of non-isomorphic top local cohomology modules H\frak adim(M)(M), for all ideals \frak a of R. It is also shown that for a given integer r ≥ 0, if H\frak ar(R/ \frak p) is zero for all \frak p in Supp (M), then H\frak a i(M)=0 for all ir.
