WebSep 26, 2024 · Geometrically, the fundamental braid has the property that any two strands cross positively exactly once. For a braid group of about four strands it is easy to show that the square of the fundamental braid commutes with the generators, using the braid relations (I have used the Artin presentation). How can this be generalized? WebJun 6, 2024 · Braid group relations.
