报告摘要：

In this lecture, we first introduce a new analytical package of contact instantons to the study of contact topology and contact dynamics via the entanglement structure of Legendrian links. As an application, we explain a general existence scheme of Reeb chords between any pair $(\psi(R), R))$ of compact Legendrian submanifold $R$ and contactomorphism $\psi$ isotopic to the identity. As a corollary we give the proof of Shelukhin's conjecture via the geometric operation of Legendrianization of contactomorphisms.
