On Chern-Simons Matrix Models
arXiv:math/0601390
Abstract
The contribution of reducible connections to the U(N) Chern-Simons invariant of a Seifert manifold can be expressed in some cases in terms of matrix integrals. We show that the U(N) evaluation of the LMO invariant of any rational homology sphere admits a matrix model representation which agrees with the Chern-Simons matrix integral for Seifert spheres and the trivial connection.
