A contact structure on an odd-dimensional manifold is a maximally non-integrable hyperplane field that vanishes nowhere. In dimension three, this structure distinguishes two special classes of knots: Legendrian knots and transverse knots. In this talk, I will discuss problems related to Legendrian and transverse knots.
