"Gray's theorem and contact Hamiltonians"

 

We will make some remarks on Gray's theorem, which Leandro proved last Tuesday, and we will see an example where Gray stability theorem is true only for the contact structure but not the contact form.  Later, we will discuss a new technique to prove contact isotopy extension theorem--contact Hamiltonian, and see how to prove results with this.
