Web• LFC:Ifalinear order has the ﬁxed point property then it is complete. • DS:Ifalinear order has no inﬁnite descending sequences then it is a well ordering. • LDF= F: Every linearly orderable Dedekind ﬁnite set is ﬁnite. • PDF: ∀X,ifP(X) is Dedekind ﬁnite then every subset of P(X) which is linearly ordered by ⊆ has a ... WebIn mathematics, an ordered field is a field together with a total ordering of its elements that is compatible with the field operations. The basic example of an ordered field is the field of real numbers, and every Dedekind-complete ordered field is isomorphic to the reals.. Every subfield of an ordered field is also an ordered field in the inherited order.
