... Can we generalize this process to arbitrary division rings? • Recall that a division ring satisfies all of the axioms of a field except that multiplication is not required to be commutative. • Over a field, if f(x) is a monic polynomial of degree n, with n distinct roots 1,..., n , f (x) (x ...
