Abstract:
Motivated by the work of M. Gross on topological Mirror Symmetry, we describe some piece-wise smooth local Lagrangian models of singular torus fibrations. In order to understand them better, we also develop some tools which generalize the notion of action-angle coordinates of smooth fibrations.
