Thus, the trivial link with n components is represented by the pair (l ,n), and the unknot is represented by (si$2 * * • s n i , n) for any n, where si,$2, • • • > sn_i are the usual generators for Bn. The second example shows that the correspondence of (b, n) with b is many-to-one, and a theorem of A. Markov [15] answers, in theory, the question of when two braids represent the same link. A Markov move of type 1 is the replacement of (6, n) by (gbg~, n) for any element g in Bn, and a Markov…

In this paper, we give a recursive formula for the Jones poly- nomial of a 2-bridge knot or link with Conway normal form C(i2n1, 2n2, i2n3,...,(i1) r 2nr) in terms of n1,n2,...,nr. As applications,

The Jones polynomial of an oriented link K is the element V(K) of Z[t) defined by tV(K+) Γ V(K_) + (t' rι^)V(K0) = 0 V(U) = 1, where U is the unknot and K+, K_, and Ko are oriented links identical
The Jones polynomial of ribbon links
For every n-component ribbon link L we prove that the Jones polynomial V(L) is divisible by the polynomial V(O^n) of the trivial link. This integrality property allows us to define a generalized
