| Abstract: |
| In this talk, I will discuss some blow-up results for a Nakao-type semilinear weakly coupled system. In particular, we consider the case when a wave equation is coupled with a damped wave equation with a time-dependent coefficient for the damping term. We investigate the influence of a scattering producing/scale-invariant damping term on the blow-up region for power nonlinearities and for derivative-type nonlinear terms. |
