Krull's principal ideal theorem, often abbreviated as the PIT, is a statement about a property (condition) that Noetherian rings satisfy. Krull also came up with a class of integral domains, called Krull domains, which satisfy the property.


A study of rings satisfying PIT was undertaken, for instance, in the paper On the generalized principal ideal theorem and Krull domains by Anderson, Dobbs, Eakin and Heinzer.


Definition with symbols

A commutative unital ring R is said to satisfy PIT or satisfy the Principal Ideal Theorem if given x \in R, and given P as a prime ideal minimal amoung the primes containing x, the codimension of P is at most 1.
