order (of a ring)

The order of a ring $R$ is the order (http://planetmath.org/OrderGroup) of its additive group, i.e. (http://planetmath.org/Ie) the number of elements of $R$ . The order of $R$ can be denoted as $|R|$ . If $|R|$ is finite, then $R$ is said to be a finite ring.

This definition of order is not necessarily standard. Please see http://planetmath.org/?op=getobj&from=corrections&id=12149this correction and the posts attached to it for more details.

释义	order (of a ring) The order of a ring $R$ is the order (http://planetmath.org/OrderGroup) of its additive group, i.e. (http://planetmath.org/Ie) the number of elements of $R$ . The order of $R$ can be denoted as $\|R\|$ . If $\|R\|$ is finite, then $R$ is said to be a finite ring. This definition of order is not necessarily standard.
