👉 In mathematics, a Krull ring is an integral domain that contains no proper subring of zero. It can be defined as follows:
A Krull ring (also called a Krull domain) is a commutative ring R with unity such that if R has a prime ideal P, then every non-zero element x in R satisfies the equation x^2 = 0.
In other words, a Krull ring is an integral domain that is closed under the operations of addition and multiplication by
