Talk:Integrally closed

From Wikipedia, the free encyclopedia

There is another definition of integral closure in algebraic number theory.

And in algebraic geometry/commutative algebra. I am adding that one.

The definition for ordered groups is unclear. What is written can be interpretted as: "for all a and b in G, and all natural n, (if a^n < b then a < 1 )"

I think what is intended is: "for all a and b in G, ( if for all natural n (a^n < b) then a < 1 )"

Someone should look into this.
