| Abstract | The Chern-Simons invariant is an interesting invariant for 3-dimensional manifold. In particular, it defines a natural complex valued invariant with volume for hyperbolic manifold of finite volume. The behavior of this complex valued Chern-Simons invariant was studied by Meyerhoff and Yoshida when it was understood as a function over deformation space of incomplete hyperbolic structures. In my talk, I will explain a corresponding result for Schottky hyperbolic manifold, which has an infinite volume and a boundary Riemann surface. I will also explain a relationship of this result with the work of Takhtajan-Zograf in Teichmuller theory. This result is a joint work with A. Mcintyre. |
