摘要：A Legendrian link in a contact 3-manifold is a smooth link that is tangent to the contact structure at every point. In anovertwisted contact 3-sphere, a Legendrian link is called "exceptional" if its complement is tight. It is considered "strongly exceptional" if its complement is tight and does not have Giroux torsion.In this talk, I will present classification result about strongly exceptional Legendrian representatives of connected sum of two Hopf links. This is joint ongoing work with Sinem Onaran.
