Chong Yang,Xi-Yang Xie
Figure 5. Dark-three solitons via solutions (34) with the parameters: (a) n = 3, ς = 0, κ = 1, η = 0.5, λ1 = 0.125, λ2 = 0.5, λ3 = 0.75, ρ1=12(12374i), ρ2=12(12152i), ρ3=12(123i), a(x) = 0.1, c(x) = 0.2 and f(x) = 0.1; (b) Parameters are the same as (a) except for a(x) = 0.7x.
