Research Abstract

1. Usual entropy always vanishes for nonintegrable plane fields (Zung 2011). We proposed a new definition of entropy which is involved in differentiability.
2. We introduced the concept of sensitive dependence on initial conditions (SDIC) for nonintegrable plane fields and constructed a nontrivial candidate for SDIC.
3. Given a contact manifold M and a torus T with a nonsingular flow, we constructed a contact form on M which defines the given contact structure and admits T as an invariant set of the associated Reeb flow.
