Figure 1From: Nonlocal-derivative NLS equations and group-invariant soliton solutionsMotion of the one-soliton for the nonlocal two-place DNLS equation (23). The green one is the density distributions \(|q|^{2}\) for \(t=0\) and the red one is for \(t=1\) with \(k_{1R}=1\), \(k_{1I}=2\)Back to article page
