131. Luis Felipe Tabera:
Tropical constructive Pappus' theorem.

Submission: 2005, December 12.

Abstract:
In this paper, we state a correspondence between classical and tropical Cramer's rule. This correspondence will allow us to compare linear geometric constructions in the projective and tropical spaces. In particular, we prove a constructive version of Pappus' theorem, as conjectured by Ritcher-Gebert, Sturmfels and Theobald.
