The author studies the fibers of the canonical morphism Spec r  → Spec r A, for an excellent ring A, and computes its images. Two applications are given: an existence theorem for real valuations in excellent rings, and an Artin-Lang homomorphism theorem for global analytic functionsCônes locaux et complétionsjournal articlemetadata only access512.7512.71Speccompletion of an excellent local ringreal spectrumlocal conesreal valuations in excellent domainsGeometria algebraica1201.01 Geometría Algebraica
