Abstract: Let be a Noetherian ring,
be an ideal of
and
be a finitely generated
-module. The aim of this paper is to show that if
is the least integer such that neither
nor
is non-finite, then
has finitely many associated primes. This combines the main results of Brodmann and Faghani and independently of Khashyarmanesh and Salarian.
