The Kontsevich integral for bottom tangles in handlebodies

Abstract : The Kontsevich integral is a powerful link invariant, taking values in spaces of Jacobi diagrams. In this paper, we extend the Kontsevich integral to construct a functor on the category of bottom tangles in handlebodies. This functor gives a universal finite type invariant of bottom tangles, and refines a functorial version of the Le-Murakami-Ohtsuki 3-manifold invariant for Lagrangian cobordisms of surfaces.
