ring having (Krull) dimension 1.
# If p is an ordinary prime number, the ring of p-adic integers is an example of a discrete valuation ring, and consequently a regular local ring. In contrast to the example above, this ring does not contain a field.
# More generally, if k is a field and X₁, X₂, ..., X_d are indeterminates, then the ring of formal power series k is a regular local ring having (Krull) dimension d.
# Still more generally, if A is a regular local
