Fix an integer \(r>1\). The 3-manifold invariant \(\tau_ r\) assigns a complex number \(\tau_ r(M)\) to each oriented, closed, connected 3- manifold \(M\) and satisfies: (1) \(\tau_ r(M\#N)=\tau_ r(M)\cdot\tau_ r(N)\); (2) \(\tau_ r(-M)=\overline{\tau_ r(M)}\); (3) \(\tau_ r(S^ 3)=1\).
\(\tau_ r(M)\) is defined as a weighted average of colored, framed link invariants \(J_{L,k}\) of a framed link \(L\) for \(M\), where a coloring of \(L\) is an assignment of integers \(k_ i\), \(0<k_ i<r\), to the components \(L_ i\) of \(L\). The \(k_ i\) denote representations of the Hopf algebra of dimension \(k_ i\), and \(J_{L,k}\) is a generalization of the Jones polynomial of \(L\) at \(q\). The authors describe the Reshetikhin-Turaev version of \(\tau_ r\) for \(q=e^{2\pi i/r}\), giving a cabling formula, a symmetry principle, and evaluations at \(r=3,4\) and \(6\).
