Inward/outward Energy Theory of Wave Equation in Higher Dimensions

Abstract

We consider the semi-linear, defocusing wave equation ${\partial }_t^{2}u-\Delta u=-|u{|}^{p-1}u$ in ${\mathbb{R}}^d$ with $1+4/(d-1)\le p<1+4/(d-2)$. We generalize the inward/outward energy theory and weighted Morawetz estimates in 3D to higher dimensions. As an application we show the scattering of solutions if the energy of initial data decays at a certain rate as $|x|\to \infty$.
