Title: Computing convex hulls in the affine building of $SL_d$

Abstract:

Faltings introduced a notion of convexity in the affine building of $SL_d$, which describes the relations among a finite collection of invertible matrices over a discrete valued field. We describe an algorithm for realizing these convex hulls as tropical polytopes in an ambient tropical space.
