Global existence and nonexistence for nonlinear wave equations with damping and source terms

Abstract: Abstract. We consider an initial-boundary value problem for a nonlinear wave equation in one space dimension. The nonlinearity features the damping term |u| m−1 ut and a source term of the form |u| p−1 u, with m, p > 1. We show that whenever m ≥ p, then local weak solutions are global. On the other hand, we prove that whenever p > m and the initial energy is negative, then local weak solutions cannot be global, regardless of the size of the initial data.

“…2, 5, 7, and 22). However, when both damping and source are present, the analysis of their interaction and their influence on the global behavior of solutions becomes more difficult and has served as a motivation for this study (see also other related results 8,17,26,31,34,35 and the references therein).…”

“…We finish the literature overview by mentioning that there exists a huge literature regarding hyperbolic equations which involves degenerate source and damping terms. Here, we cite, for example . The majority of these papers deal with existence, nonexistence and blow‐up of solutions in finite time.…”
