Definition talk:Trivial Norm

a) Worth linking to the Definition:Discrete Metric? It's very similar in concept.

b) Is there a reason why a norm can be defined only on a division ring? I'm currently (while thinking of something else) vaguely wondering if there's a reason why we can't impose a norm on the integers. (there's probably an obvious one which I can't think of.) --prime mover 14:51, 1 December 2011 (CST)
