Blow-up behavior outside the origin for a semilinear wave equation in the radial case
✍ Frank Merle; Hatem Zaag 📂 Article 📅 2011 🏛 Elsevier Science 🌐 French ⚖ 190 KB

We consider the semilinear wave equation in the radial case with conformal subcritical power nonlinearity. If we consider a blow-up point different from the origin, then we exhibit a new Lyapunov functional which is a perturbation of the one-dimensional case and extend all our previous results known
