Three-dimensional BF Theories and the Alexander-Conway Invariant of Knots
A. S. Cattaneo, P. Cotta-Ramusino, M. Martellini
We study 3-dimensional BF theories and define observables related to knots and links. The quantum expectation values of these observables give the coefficients of the Alexander-Con…

Moduli Spaces of Curves with Homology Chains and c=1 Matrix Models
A. S. Cattaneo, A. Gamba, M. Martellini
We show that introducing a periodic time coordinate in the models of Penner-Kontsevich type generalizes the corresponding constructions to the case of the moduli space ${\cal S}_{g…
