Solitons in the Calogero-Sutherland Collective-Field Model
  In the Bogomol'nyi limit of the Calogero-Sutherland collective-field model we find static-soliton solutions. The solutions of the equations of motion are moving solitons, having no static limit for $\l>1$. They describe holes and lumps, depending on the value of the statistical parametar $\l$.
