摘 要：

In the 1960s several authors, including Fadeev and Ikebe, proved an important condition for quantum scattering called asymptotic completeness. This roughly states: what comes in must come out. That is in a scattering problem, your initial state looks like separated particles. They scatter and asymptotic completeness tells us that separated particles come out again (with many caveats). In this talk, I will retell this story for solitons. Solitons are particle-like objects who owe their stability and existence to the topology of the underlying system. To describe asymptotic completeness for solitons I will explain what solitons and quantum solitons are, what quantum soliton scattering is and give many examples to illustrate these ideas. This will naturally lead us to the definition of a Quantum Soliton Scattering Manifold. Having understood this, I will show that some old proposals for describing soliton scattering are unsuitable and propose some new ideas.
