Dark solitons on the general nonzero background. Here (a), (b), and (c) are the model square map of single dark soliton for q₁₁, q₂₁, and q₃₁, respectively; (d), (e), and (f) are the model square map of two dark solitons for q₁₂, q₂₂, and q₃₂, respectively. The parameters c₁ = 5, c₂ = 1, c₃ = 1, a₁ = −0.1, a₂ = 0.1, a₃ = 0.8.
