Résumé
Title: Affine buildings from real algebraic geometry
Abstract: The theory of symmetric spaces and the theory of buildings have a rich history of parallels and interactions. We describe symmetric spaces in terms of real algebraic geometry and then replace the real numbers by valued real closed fields to construct an affine Λ-building. A key tool is a transfer principle from model theory.
