Abstract | |
Let (R, m) be a commutative Noetherian local ring, M be a finitely generated R-module and a, I and J are ideals of R. We investigate the structure of formal local cohomology modules of F-a,F-I,(i)(J) (M) and (sic)(a,I),(i)(J) (M) with respect to a pair of ideals, for all i >= 0. The main subject of the paper is to study the finiteness properties and artinianness of F-a,I,J(i) (M) and (sic)(a,m,J)(i) (M). We study the maximum and minimum integer i is an element of N such that F-a, m, J(i) (M) and (sic)(a, m, J)(i) (M) are not Artinian and we obtain some results involving cosupport, coassociated and attached primes for formal local cohomology modules with respect to a pair of ideals. Also, we give an criterion involving the concepts of finiteness and vanishing of formal local cohomology modules and Cech-formal local cohomology modules with respect to a pair of ideals. (AU) | |
