| Abstract: | We construct the soliton solution and smooth positon solution of the second-type derivative nonlinear Schr?dinger (DNLSII) equation. Additionally, we present a detailed discussion about the decomposition of the positon solution, and display its approximate orbits and variable "hase shift". The second and third order breather-positon solutions are also constructed. |
