Galois fields and galois rings made easy pdf
WebFields, Ideals, and Quotient Rings By definition, a field is just a commutative ring in which every nonzero element has an inverse. An ideal in a ring R is a nonempty subset J of R satisfying: (a) a b 2J for all a;b 2J (closure under subtraction); (b) ra and ar are in J, for all a 2J, r 2R (closure under outside multiplication).
