We study the behavior at infinity of the solutions of damped Kirchhoff equation when the nonlinearity is a power. We prove that the renormalized solutions have a non-zero limit and that the norm of this limit does not depend on the initial data. Moreover we obtain a new (optimal) estimate on the second in time derivative of the solution.

Abstract
We study the behavior at infinity of the solutions of damped Kirchhoff equation when the nonlinearity is a power. We prove that the renormalized solutions have a non-zero limit and that the norm of this limit does not depend on the initial data. Moreover we obtain a new (optimal) estimate on the second in time derivative of the solution.File in questo prodotto:
