+(*#* * The Real Number Structure
+
+We will now apply our Cauchy sequence construction to an archimedean ordered field in order to obtain a model of the real numbers.
+
+** Injection of [Q]
+
+We start by showing how to inject the rational numbers in the field of Cauchy sequences; this embedding preserves the algebraic operations.
+
+%\begin{convention}% Let [F] be an ordered field.
