New solitary waves for the Klein–Gordon–Zakharov equations.

This paper studies new solitary waves for the Klein–Gordon–Zakharov equations. The obtained results are diverse and some specific ones emerge as dark, bright and bell-shape. The two integration schemes lead to obtaining waves which propagate without deformation as illustrated in graphical representations. Our obtained results are more specific compared to those obtained by Refs. 8 and 31 [C. H. Zhao and Z. M. Sheng, Acta Phys. Sin.53 (2004) 29; S. Yakada, B. Depelair, G. Betchewe and S. Y. Doka, Optik197 (2019) 163108]. [ABSTRACT FROM AUTHOR]
