Blow-up behavior for the Klein-Gordon and other perturbed semilinear wave equations
arXiv:1301.0471
Abstract
We give blow-up results for the Klein-Gordon equation and other perturbations of the semilinear wave equations with superlinear power nonlinearity, in one space dimension or in higher dimension under radial symmetry outside the origin.
