Lump-soliton, lump-multisoliton and lump-periodic solutions of a generalized hyperelastic rod equation

摘要

In this paper, we will obtain lump-soliton solution for (1 + 1)-dimensional generalized hyperelastic rod equation, also known as generalized KdV equation by aid of Hirota bilinear method (HBM). We also obtain lump-multisoliton (which is an interaction of lump with one kink or two kink soliton) and lump-periodic solutions (which is formed by an interaction between lump and periodic waves). The dynamics of these solution are examined graphically by selecting significant parameters.
