The Artinianess of graded generalized local cohomology modules This talk wants to present the Artinianess of some classes of graded generalized local cohomology modules. Generalized local cohomology was introduced by J. Herzog in 1974. It is a generalization of Grothendieck's local cohomology theory. In particular, we consider it for a given Noetherian commutative local ring R with the unit element 1 different from 0, for each pair of modules M, N over R. A recent result of the speaker is that under certain additional assumptions, this cohomology vanishes in high enough dimensions. This allows to obtain partial information about the projective dimension of M and the Krull dimension of N. .
