The Threshold between Effective and Noneffective Damping for Semilinear Waves

Analysis of PDEs 2015-09-10 v2

Abstract

In this paper we study the global existence of small data solutions to the Cauchy problem for the semilinear wave equation with scale-invariant damping. We obtain estimates for the solution and its energy with the same decay rate of the linear problem. We extend our results to a model with polynomial speed of propagation and to a model with an exponential speed of propagation.
