... We use the graph description of coordinates on Teichmuller spaces of Riemann surfaces with holes due to Penner and Fock. ... The Goldman's Poisson structure can be recovered; its quantum deformation enables us to introduce noncommutative Teichmuller spaces and to construct the quantum mapping class group and quantum modular transformations. Using the geodesic spectral description, we can find a cell decomposition of Teichmuller (and moduli) spaces in the new coordinates. ...
