内容摘要:
In this talk, I will show how notions of the Yang-Baxter eqaution and the reflection equation, that are essential tools in the quantum integrable theories, arise in the context of classical soliton models. The celebrated vector nonlinear Schrödinger (VNLS) equation, also known as Manakov model, will be the main model under investigation. Precisely, N-soliton solutions of VNLS without boundary will be used for the construction of Yang-Baxter maps, ie, solutions of the Yang-Baxter equation. Soliton solutions of VNLS on the half-line with integrable boundary conditions will be used for the construction of reflection maps, ie, solutions of the reflection equation. The emphasis will be on the nature of boundary problems for integrable systems.
