Let (R, m) be a complete Noetherian local ring, I an ideal of R and M a nonzero Artinian R-module. In this paper it is shown that if p is a prime ideal of R such that dim R/p = 1 and (0:M p) is not finitely generated and for each i 2 the R-module Ext R i (M,R/p) is of finite length, then the R-module Ext R 1 (M, R/p) is not of finite length.

Abstract. Let a and b be ideals of a commutative Noetherian ring R and M a �nitely generated R-module of �nite dimension d > 0. In this paper, we obtain some results about the annihilators and attached primes of top local cohomology and top formal local cohomology modules. In particular, we determine Ann(b Hda(M)), Att(bHda(M)) andAtt(bFda(M)).(M))...

Let a be an ideal of a commutative Noetherian ring R and M a finitely generated R-module. In this paper we proved that if Supp F i a (M) has finite for all i < t, then Ass(F t a (M)) is finite.

Let a be an ideal of local ring (R, m) and M a finitely generated R-module and n ∈ N. It is shown that some results concerning cominimaxness of formal local cohomology modules.

Let a be an ideal of local ring (R; m) and M a finitely generated R-module and n an integer. It is shown that some results concerning cominimaxness of formal local cohomology modules.

Let a be an ideal of a commutative Noetherian ring R and M a finitely generated R-module. In this paper we proved that if Supp F (M) has finite for all i < t, then Ass(Fta (M)) is finite

In recent years, many researchers have focused on wireless sensor networks and their applications. To obtain scalability potential in these networks most of the nodes are categorized as distinct groups named cluster and the node which is selected as cluster head or Aggregation Node offers the operation of data collection from other cluster nodes an...
