Decay estimates for a Klein-Gordon model with time-periodic coefficients

Analysis of PDEs 2021-05-10 v1

Abstract

In this paper we consider a Klein-Gordon model with time-dependent periodic coefficients. The aim is to investigate how the presence of the mass term influences energy estimates with respect to the case of vanishing mass, already treated in [18]. The approach is based on a diagonalisation argument for high frequencies and a contradiction argument for bounded frequencies.
