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