Idea

A discrete valuation ring is a principal ideal domain which has exactly one non-zero maximal ideal. This means that it is a local principal ideal domain, or equivalently, a local integral domain with a Dedekind-Hasse norm.

 Properties

Every discrete valuation ring is a local integral domain.

The ring of formal power series of a field is a discrete valuation ring.
