The origins of contact and symplectic topology stem from Hamilton's reformulation of classical mechanics. Contact topology is the study of geometric structures on odd dimensional smooth manifolds given by a maximally nonintegrable hyperplane field described as the kernel of a 1-form; these hyperplane fields are called contact structures. The associated one form is called a contact form and it uniquely determines a Hamiltonian-like vector field called the Reeb vector field on the manifold. I’ll review all of this and more in my talk which will feature numerous graphics.
