Abstract
Let be a commutative noetherian ring and an ideal of . Assume that for all integers the local cohomology module is -cofinite. Suppose that is a regular local ring for all prime ideals that do not contain . In this paper, we prove that if the -cofinite modules forms an abelian category, then for all finitely generated -modules and all integers , the local cohomology module is -cofinite.
