Improvement on the blow-up for a weakly coupled wave equations with scale-invariant damping and mass and time derivative nonlinearity
Makram Hamouda, Mohamed Ali Hamza
An improvement of [18] on the blow-up region and the lifespan estimate of a weakly coupled system of wave equations with damping and mass in the scale-invariant case and with time-…
Nonexistence result for the generalized Tricomi equation with the scale-invariant damping, mass term and time derivative nonlinearity
Moahmed Fahmi Ben Hassen, Makram Hamouda, Mohamed Ali Hamza +1
In this article, we consider the damped wave equation in the \textit{scale-invariant case} with time-dependent speed of propagation, mass term and time derivative nonlinearity. Mor…
A note on the nonexistence of global solutions to the semilinear wave equation with nonlinearity of derivative-type in the generalized Einstein-de Sitter spacetime

In this paper, we establish blow-up results for the semilinear wave equation in generalized Einstein-de Sitter spacetime with nonlinearity of derivative type. Our approach is based…
Blow-up and lifespan estimate for the generalized Tricomi equation with mixed nonlinearities
Makram Hamouda, Mohamed Ali Hamza
We study in this article the blow-up of the solution of the generalized Tricomi equation in the presence of two mixed nonlinearities, namely we consider $$ (Tr) \hspace{1cm} u_{tt}…
A blow-up result for the wave equation with localized initial data: the scale-invariant damping and mass term with combined nonlinearities
