The Hilbert-Samuel function of a nonzero finitely generated module over a commutative Noetherian local ring
with maximal ideal
, with respect to an
-primary ideal
, is the map
such that, for all
,
where
denotes module length. It is related to the Hilbert
function of the associated graded module
by the identity
For sufficiently large , it coincides with a polynomial
in
of degree equal to the Krull
dimension of
.
