Bruhat-Tits buildings can be viewed as a geometric interpretation of semisimple linear algebraic groups over fields with a non-Archimedean valuation. In particular, they are strongly linked to number theory and arithmetic geometry. 

 

They also form an interesting and important class of examples of spaces of nonpositive curvature, and as such have implications also for geometric group theory.

 

The meeting consisted of four lecture series and two 1-hour lectures on different aspects of this theory given by leading experts. The speakers are: Ramla Abdellatif, Linus Kramer, Bernhard Mühlherr, Bertrand Rémy, Guy Rousseau and Anne Thomas.  

 

We thank everyone who attended and made it a great week!
