Abstract The aim of this paper is to derive energy estimates for solutions of the Cauchy problem for the Klein–Gordon type equation ut t 4uCm(t)2u D 0. The coefficient m is given by m(t)2 D (t)2 C p(t) with a decreasing, smooth shape function and an oscillating, smooth and bounded perturbation function p. We study under which assumptions for and p one can expect results about a generalization of energy conservation. The main theorems of this note deal with m belonging to C M , M 2, and m belonging to the Gevrey class (s), s 1.
