Canonical
A mathematical object is said to be canonical if it arises in a natural way without introducing any additional objects.
Examples
- Suppose
is the Cartesian product
of sets 
.
Then 
has two canonical projections
and
defined in a natural way. Of course, if
we assume more structure
of 
there are also other projections.
- canonical projection (in group theory)
Notes
For a discussion of the theological use of canonical, see [1].
