Octagon and tropical octagon yield braid invariants
Abstract
In the present paper, we construct an invariant of braids in the real projective plane which corresponds to an ``action'' of braids on certain graphs in P2 with labels. This paper is a sequel of papers M,KM. It demonstrates once more that solutions to the octagon relation in various forms give rise to invariants of braids.
