Carath\'eodory, Helly and the others in the max-plus world

Understand

Carath\'eodory's, Helly's and Radon's theorems are three basic results in discrete geometry.

• Their max-plus counterparts have been proved by various authors.
• In this paper, more advanced results in discrete geometry are shown to have also their max-plus counterparts: namely, the colorful Carath\'eodory theorem and the Tverberg theorem.
• A conjecture connected to the Tverberg theorem -- Sierksma's conjecture --, although still open for the usual convexity, is shown to be true in the max-plus settings.
