The purpose of this paper is to describe all the valuation rings of A which are compatible with some prime cone of A, i.e., to give a description of all the points of the real Riemann surface Sr(A/R). Furthermore, we explain the geometric meaning of these points and indicate the specialization relations among them.”book parthttp://www.ams.org/books/conm/155/http://www.ams.orgmetadata only access512.7Geometria algebraica1201.01 Geometría Algebraica
