Abstract
Let phi : k > A and f : A > R be ring morphisms, R a real ring. We prove that if f : A > R is etale, then the corresponding mapping between real Riemann surfaces Sr(f) : Sr(R/k) > Sr(A/k) is a local homeomorphism. Several preparatory results are proved, as well. The most relevant among these are: (1) a Chevalley's theorem for real Riemann surfaces on the preservation of constructibility via Sr(f), and (2) an analysis of the closure operator on real Riemann surfaces. Constructible sets are dealt with by means of a suitable firstorder language.
