Abstract:

This paper is concerned with the existence and the nonlinear asymptotic stability of traveling wave solutions to the Cauchy problem for a system of dissipative evolution equations 

with initial data and end states
(ξ, θ)(x, 0) = (ξ0, θ0)(x)→ (ξ±, θ±) as x→±∞.
We obtain the existence of traveling wave solutions by phase plane analysis and show the asymptotic nonlinear stability of traveling wave solutions without restrictions on the coefficients α and v by the method of energy estimates.

Key words: dissipative evolution equations, traveling wave solutions, nonlinear stability, energy estimates
