The dominance relation on a set of points in Euclidean -space is the intersection
of the
coordinate-wise orderings. A point
dominates a point
provided that every coordinate of
is at least as large as the corresponding coordinate of
.
A partition dominates a partition
if, for all
, the sum of the
largest parts of
is
the sum of the
largest parts of
.
For example, for
,
dominates all other partitions,
while
is dominated by all others.
In contrast,
and
do not dominate each other (Skiena
1990, p. 52).
The dominance orders in
are precisely the partially ordered sets
of dimension at most
.
