The paper investigates a class of a semilinear wave equation with time-dependent damping term () and a nonlinearity . We will show the influence of…
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…
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
