In this paper we develop
a method for constructing latticeordered fields (“ℒ-fields”) which are not
totally ordered (“o-fields”) and hence are not f-rings. We show that many
of these fields admit a Hahn type embedding into a field of formal power
series with real coefficients. In order to establish such an embedding we
make use of the valuation theory for abelian ℒ-groups and prove the “well
known” fact that each o-field can be embedded in an o-field of formal power
series.
