On Reidemeister torsion of a symplectic complex

Let $S$ be a compact surface with genus at least 2. We consider the Teichmüller space $\teich(S)$ of $S$. By fixing a maximal geodesic lamination, in [1] we showed the relation between the Weil-Petersson and Thurston symplectic forms. In this talk, we will explain the relation between Reidemeister torsion and Pfaffian of Weil-Petersson form and hence Pfaffian of Thurston symplectic form.
