Abstract:
Let Mn(K) be the hyperbolic 3-manifold obtained by n-cyclic covering of S3 branched over a hyperbolic knot K. A method to compute the volume and the Chern-Simons invariant of Mn(K) is given. The value of the volume of Mn is n times the value of the volume of the corresponding hyperbolic orbifold. This volume can be obtained by appying the Schläffli Formula for the volume to the cone-manifold family, (K,α ), with singularity K. The same approch is followed for the Chern-Simons invariant, after proving a "Schläffli Formula" for a generalized Chern-Simons function on the family of cone-manifold structures (K,α ).
