Abstrakt: Abstract: Let I be an ideal of a commutative Noetherian ring R. It is shown that the R-modules H jI (M) are I-cofinite for all finitely generated R-modules M and all j 0 if and only if the R-modules Ext iR (N,H jI (M)) and Tor iR (N, H jI (M)) are I-cofinite for all finitely generated R-modules M, N and all integers i, j 0.
