Ideal Height


The notion of height is defined for proper ideals in a commutative Noetherian unit ring R. The height of a proper prime ideal P of R is the maximum of the lengths n of the chains of prime ideals contained in P,

 P_0 subset P_1 subset ... subset P_n=P.

The height of any proper ideal I is the minimum of the heights of the prime ideals containing I.
