Abstract

Astrophysics and Astroparticles general Original Paper Physics Physics and Astronomy
In this paper, two models with fourth-order dispersion in 2 + 1 dimensions are investigated. Based on Ansatz method, exact domain wall solutions are derived. Parametric conditions for the existence of the domain wall solutions are given. Lie symmetry analysis also retrieves conserved densities of governing nonlinear evolution equations.
