Minimal prime ideal

Summary

A minimal prime ideal of a commutative ring is a prime ideal that contains no smaller prime ideal. Every prime ideal contains a minimal prime, and the nilradical is the intersection of the minimal primes. Geometrically, the minimal primes correspond to the irreducible components of the spectrum. A Noetherian ring has only finitely many minimal primes.
