Some observations about symplectic combinatorial manifolds.

This line of studies was initiated by Yasha Eliashberg. The central object of this talk is a piecewise constant Withney symplectic form on a combinatorial manifold. Basic questions are whether such symplectic structures satisfy Darboux and can be used to triangulate smooth symplectic manifolds. Some answers will be provided. This is a joint work with Julie Distexhe.
