Abstract
In the paper by Guzy and Point, Differential topological fields, the model-completion ( OVF ) D ∗ of the theory of ordered valued differential fields OVF D is established. Models of this theory are closed ordered differential fields (the theory CODF was studied by Singer) which have a non-trivial convex (for the order) subring as valuation ring. Here we prove the valued analogue of a result of Singer: if K is a model of ( OVF ) D ∗ then K ( i ) ( i 2 = − 1 ) is a model of the theory of differentially closed valued fields which is the model-completion of the theory of non-trivially valued differential fields of characteristic zero.
