Abstract

We give an algorithm, with a singly exponential complexity, deciding whether a tropical linear prevariety is a tropical linear variety. The algorithm relies on a criterion to be a tropical linear variety in terms of a duality between the tropical orthogonalization \(A^\perp \) and the double tropical orthogonalization \(A^{\perp \perp }\) of a subset A of the vector space \(({{\mathbb {R}}}\cup \{ \infty \})^n\). We also give an example of a countable family of tropical hyperplanes such that their intersection is not a tropical prevariety.
