Convexity of tropical polytopes
Marianne Johnson, Mark Kambites
We study the relationship between min-plus, max-plus and Euclidean convexity for subsets of . We introduce a construction which associates to any max-plus convex set…

We prove that a monoid is sofic, in the sense recently introduced by Ceccherini-Silberstein and Coornaert, whenever the J-class of the identity is a sofic group, and the quotients…

We introduce and study a strong "thin triangle"' condition for directed graphs, which generalises the usual notion of hyperbolicity for a metric space. We prove that finitely gener…
