A commutative unital ring is termed one-dimensional if it satisfies the following equivalent conditions:

  • Its Krull dimension is one
  • Every prime ideal in it is either a minimal prime ideal or a maximal ideal, and not every prime ideal is both (i.e. there exists at least one minimal prime ideal that is not maximal, or at least one maximal ideal that is not a minimal prime)
