Blow up and lifespan estimates for systems of semi-linear wave equations with dampings and potentials (2209.02920v1)
Published 7 Sep 2022 in math.AP
Abstract: In this paper, we consider the semi-linear wave systems with power-nonlinearities and space-dependent dampings and potentials. We obtain the blow-up regions for three types wave systems as well as the lifespan estimates.
