Integral closure of an ideal
text:
In algebra, the integral closure of an ideal I of a commutative ring R, denoted by I ¯ , is the set of all elements r in R that are integral over I: there exist a i ∈ I i such that It is similar to the integral closure of a subring. For example, if R is a domain, an element r in R belongs to I ¯ if and only if there is a finitely generated R-module M, annihilated only by zero, such that r M ⊂ I M . It follows that I ¯ is an ideal of R I is said to be integrally closed if I = I ¯ . The integral c
