TSVP Talk: "Knots in Contact 3-Manifolds" by Sinem Onaran

Title: Knots in Contact 3-Manifolds

Abstract: Contact geometry has played a central role in the study of the topology of low-dimensional manifolds. A contact structure on an odd-dimensional manifold is a maximally non-integrable, non-vanishing hyperplane field. When the manifold has dimension three, there is a special class of knots called Legendrian knots. A knot is Legendrian if it is always tangent to the contact planes. In this talk, I will provide a brief introduction to contact 3-manifolds and the theory of Legendrian knots within them. Then, I will present recent progress and results concerning the classification of Legendrian knots. Warning: this talk contains an excessive number of knot diagrams—handle with curiosity!
