Abstract
The anomalous scattering of lump waves within the framework of the Mel’nikov equation is considered via Hirota’s bilinear method and further limits. The anomalous scattering phenomena of two lumps are studied in detail, asymptotic behavior of anomalous scattering lumps is discussed. Furthermore, several interesting patterns of high-order degenerate lumps are observed, including triangular and quadrangular peak locations. These exotic structures may enrich our understanding of the nature of lump waves.
