Abstract
In this paper, we discuss the existence and asymptotic behavior of traveling waves for a generalized Burgers–KdV equation. We show the heteroclinic orbits of the associated ordinary differential equations for the generalized Burgers–KdV equation with a special convolution kernel and then establish the existence result of traveling wave solutions for the Burgers–KdV equation by employing geometric singular perturbation theory and the linear chain trick. And the asymptotic behavior of traveling waves is obtained by using the standard asymptotic theory.
