摘要：

In the present paper, we study small data blow-up of the semi-linear wave equation with a scattering dissipation term and a time-dependentmass term from the aspect of wave-like behavior. The Strauss type criticalexponent is determined and blow-up results are obtained to both sub-criticaland critical cases with corresponding upper bound lifespan estimates. For thesub-critical case, our argument does not rely on the sign condition of dissipationand mass, which gives the extension of the result in. Moreover, we showthe blow-up result for the critical case which is a new result.
