THE FIFTH ANNUAL COLLOQUIUMFEST

Journées de l'IHP

Paris, April 5 and 6, 2004

at the Institut Henri Poincaré


This year's Colloquiumfest is organized by Zoé Chatzidakis (Equipe de Logique Mathématique, Université Paris 7), and
Franz-Viktor Kuhlmann (Research Unit "Algebra and Logic", Mathematical Sciences Group, University of Saskatchewan, currently visiting the Equipe de Géométrie et Dynamique, Institut de Mathématiques de Jussieu).


The Fifth Annual Colloquiumfest is generously supported by the Institut Henri Poincaré, the Equipe de Géométrie et Dynamique, and the Equipe de Logique Mathématique.

The emphasis of this colloquiumfest will be on

Valuation Theory in Algebraic Geometry and Model Theory.
