Ring (mathematics)

WebNote. Testing whether a quotient ring \(\ZZ / n\ZZ\) is a field can of course be very costly. By default, it is not tested whether \(n\) is prime or not, in contrast to GF().If the user is sure that the modulus is prime and wants to avoid a primality test, (s)he can provide category=Fields() when constructing the quotient ring, and then the result will behave like a field. Webideal, in modern algebra, a subring of a mathematical ring with certain absorption properties. The concept of an ideal was first defined and developed by German mathematician Richard Dedekind in 1871. In particular, he used ideals to translate ordinary properties of arithmetic into properties of sets. A ring is a set having two binary …
