On the Local Cohomology and Formal Local Cohomology Modules

Let a and b be ideals of a commutative Noetherian ring R and M be a finitely generated R-module of dimension d > 0. We prove some results concerning the top local cohomology and top formal local cohomology modules. Among other things, we determine SuppR(b Hda(M)) and SuppR(bFda(M)). Also, we obtain some relations be-tween AnnR(b Hda(M)), AttR(b Hda(M)) and SuppR(b Hda(M)) and we get similar results for bFda(M).
