Workshop Model Theory of Valued fields
5 - 9 March 2018, IHP, amphitheater Hermite

This workshop is part of the trimester Model Theory, Combinatorics and Valued fields, to be held at the Institut Henri Poincaré, 8 January - 6 April 2018. It will concentrate on the part of the programme having to do with valued fields: Model theory of Henselian valued fields with the valuation topology; Motivic integration; Algebraically closed valued fields, imaginaries, and Berkovich spaces; Valued fields with additional structure; Transseries and surreal numbers; Definable groups.

Scientific Committee

Zoé Chatzidakis (CNRS - ENS), Antoine Ducros (Sorbonne Université), Martin Hils (Münster), Tom Scanlon (UC Berkeley, chair)

This meeting is sponsored by the ASL and the NSF.
