Marvin Anas Hahn (MPI MIS, Leipzig)
Orders, polytropes and Bruhat-Tits buildings

Bruhat Tits buildings are central objects in the theory of algebraic groups that carry a rich combinatorial structure. A central role in the combinatorial investigation of Bruhat-Tits buildings is played by various different notions of convexity. In this talk, we will introduce these different notions, relate them to tropical geometry and the theory of orders.
