Soliton Resolution at Blow-Up for the Subconformal Nonlinear Wave Equation

Hatem Zaag

We consider the nonlinear wave equation (NLW) with a superlinear pure power nonlinearity in the subconformal and conformal cases. Under some conditions on initial data, this equati…

Regularity and singularity of the blow-up curve for a wave equation with a derivative nonlinearity and a scale-invariant damping

Ahmed Bchatnia, Makram Hamouda, Firas Kaabi +2

In this article, we investigate the blow-up behavior of solutions to the one-dimensional damped nonlinear wave equation, namely $$ \partial_t^2 u - \partial_x^2 u + \fracμ{1 + t} \…

Scalar behavior for a complex multi-soliton arising in blow-up for a semilinear wave equation

Asma Azaiez, Jacek Jendrej, Hatem Zaag

This paper deals with blow-up for the complex-valued semilinear wave equation with power nonlinearity in dimension 1. Up to a rotation of the solution in the complex plane, we show…
