| Abstract: | Let  be an ideal of a Noetherian local ring  and  a finitely generated  -module. The f-depth of  on  is the least integer  such that the local cohomology module  is not Artinian. This paper presents some part of the theory of f-depth including characterizations of f-depth and a relation between f-depth and f-modules. |
| Keywords: | f-depth f-modules local cohomology modules |
