In the ``Not so Short Introduction to LaTeX2E'' on
page 48 it is stated that you can get them using the
\mathbb command using amsfonts or amssymb.

I don't know if there's a standard name fo them.
Personally I use
 $\Nset$ $\Zset$, $\Qset$, $\Rset$ and $\Cset$.

Perhaps
 $\naturalnumbers$,
 $\integers$,
 $\rationalnumbers$,
 $\realnumbers$ and
 $\complexnumbers$ is a bit neater.
