ON THE FINITENESS OF FORMAL LOCAL COHOMOLOGY MODULES

Let a be an ideal of local ring (R;m) and M a nitely generated R-module. Inthis paper, we prove some results concerning niteness and minimaxness of formal local cohomologymodules. In particular, we investigate some properties of top formal local cohomologyFdimM=aMa (M) and we determine CosR(FdimM=aMa (M)), AnnR(FdimM=aMa (M)) andAttR(FdimM=aMa (M)).
