The Noether-Lasker theorem states that for a commutative Noetherian ring and a nonzero left unital
R-module
that is a finitely
generated module, there is a finite set of submodules
with the following
properties (Altman and Kleiman 2013, pp. 109-110).
1. ,
and
is not contained in
for all
.
2. Each quotient module is nonzero and
-primary for some prime ideal
of
.
3. The prime ideals are all distinct for
.
4. If
does not contain
for any
, then
is uniquely determined by
and
.
Here, -primary
means that every
acts on
either injectively or with
some positive integer power
acting as zero, and
is exactly the set of
satisfying the latter condition (Milne 2014, p. 90).
