In this paper, we consider the initial value problem for the Rosenau equation with damped term. The decay structure of the equation is of the regularity-loss type, which causes the difficulty in high-frequency region. Under small assumption on the initial value, we obtain the decay estimates of global solutions for n≥1. The proof also shows that the global solutions may be approximated by the solutions to the corresponding linear problem for n≥2. We prove that the global solutions may be approximated by the superposition of nonlinear diffusion wave for n = 1. Copyright © 2016 John Wiley & Sons, Ltd.
