WebJun 6, 2024 · The braid group on n strands, denoted B n, has a geometric/topological definition as the group whose elements are equivalence classes of n -braids (under ambient isotopy), and whose group operation is composition of braids. See Wikipedia for more details. The standard presentation of the braid group B n is Webbraid can be drawn as in the example below (where n = 4). The crucial property of a braid is that the tangent vector to the curves can never be horizontal. Braids are considered up to isotopies which are supported between the top and bottom planes. Braids on n strings form a group, called Bn, under concatenation (plus some isotopy) as below: α ...
