Definition talk:Ring with Unity

Null ring is ring with unity
The null ring is a ring with unity (and the current definition does in fact not exclude it). This is important in commutative algebra. The "also defined as" should better read "some sources do not allow [...]" --barto (talk) (contribs) 08:42, 22 December 2017 (EST)


 * A page is needed to demonstrate that a Null Ring is a Ring with Unity because it is not intuitively obvious. The naive view is that the zero and the one are different elements, and so a null ring, because it does not have a unity, is not a ring with unity. But back this up with whatever hard-copy sources you can find (preferably at the elementary level) otherwise it will may be possible to defend your case. --prime mover (talk) 10:28, 22 December 2017 (EST)
