Figure 2From: Bilinear Bäcklund transformations and explicit solutions of a \((3+1)\)-dimensional nonlinear equation Solitary periodic waves. (a) Solitary periodic wave with \(\Phi(y)= \sin(y)\), \(t=0\), \(z=0\), \(k=0.1\); (b) two solitary periodic waves with \(\Phi(y)= \sin(y)\), \(t=0\), \(z=0\), \(k_{1}=0.1\), \(k_{2}=0.3\).Back to article page
