projection
(foldoc)		projection

In domain theory, a function, f, which is (a)
idempotent, i.e. f(f(x))=f(x) and (b) whose result is no
more defined than its argument. E.g. F(x)=bottom or F(x)=x.

In reduction systems, a function which returns some
component of its argument. E.g. head, tail, \ (x,y) . x.
In a graph reduction system the function can just return a
pointer to part of its argument and does not need to build any
new graph.

three rectangular axes, and the principal planes are
parallel to three rectangular planes passing through the
three axes.
