讲座摘要：In this talk, we address the orbital stability for doubly periodic solutions of the focusing nonlinear Schrödinger equation. We first clarify the relationship between algebro-geometric and doubly periodic representations, then use the theory of squared eigenfunctions to perform a spectral analysis of the linearized operator, from which the orbital stability of these solutions follows.
