Bennequin's Conjecture

A Braid with strands and components with positive crossings and negative crossings satisfies

where

is the Unknotting Number. While the second part of the Inequality was already known to be true(Boileau and Weber, 1983, 1984) at the time the conjecture was proposed, the proof of the entire conjecture was completedusing results of Kronheimer and Mrowka on Milnor's Conjecture (and, independently, using Menasco's Theorem).
