Euclidean domain
Noun
Meaning
Euclidean domain (plural Euclidean domains)
(algebra) an integral domain in which division with remainder is possible
Examples
A Euclidean domain is an integral domain which can be endowed with at least one Euclidean function.
A field norm is a Dedekind-Hasse norm; thus, (5) shows that a Euclidean domain is a PID.
As a Euclidean domain It is easy to see graphically that every complex number is within units of a Gaussian integer.
Any Euclidean domain is a unique factorization domain (UFD), although the converse is not true.
An example of a principal ideal domain that is not a Euclidean domain is the ring Wilson, Jack C. "A Principal Ring that is Not a Euclidean Ring."
However, if there is no "obvious" Euclidean function, then determining whether R is a PID is generally a much easier problem than determining whether it is a Euclidean domain.
