A better bound on blow-up rate for the superconformal semilinear wave equation
Mohamed Ali Hamza, Hatem Zaag
We consider the semilinear wave equation in higher dimensions with superconformal power nonlinearity. The purpose of this paper is to give a new upper bound on the blow-up rate in…

Refined estimates of the blow-up profile for a strongly perturbed semilinear wave equations in one space dimension
M. A. Hamza, Omar Saidi
We consider in this paper a class of strongly perturbed semilinear wave equations with a non-characteristic point in one space dimension, for general initial data. Working in the f…
