...t R given by the map that associates (Gγ , fγ) to the string wγ for every arc γ in (S,M, T ). Such a correspondence has also been noted in the setting of a triangulation of the oncepunctured torus in =-=[R]-=-. 3. Crossing String Modules and Smoothing of Crossings for String Modules In this section we interpret the crossing of arcs in terms of the corresponding string modules in J(Q,W ). We do this by usin...
