This paper investigates a Sharma-Tasso-Olver-Burgers equation for nonlinear dispersive waves, deriving multiple solutions through auto-Backlund transformations and hetero-Backlund transformations. The influence of the coefficients on the solutions is also discussed in the study of this equation.
Burgers-type equations are considered as the models of certain phenomena in plasma astrophysics, ocean dynamics, atmospheric science and so on. In this paper, a Sharma-Tasso-Olver-Burgers equation for the nonlinear dispersive waves is studied. Based on the Painleve-Backlund equations, one auto-Backlund transformation and two hetero-Backlund transformations are derived. Motivated by the Burgers hierarchy, a Lax pair is given. Via two hetero-Backlund transformations with different constant seed solutions, we find some multiple-kink solutions, complex periodic solutions, hybrid solutions composed of the lump, periodic and multiple kink waves. Then we discuss the influence of the coefficients of the above equation on such solutions. Via the auto-Backlund transformation with the nontrivial seed solutions, we obtain certain lump-type solutions, kink-type solutions and recurrence relation of the above equation.
