Abstract:

In this paper, we investigate the blow-up of solutions to a semilinear double-wave equation with a nonlinear memory term. By establishing some auxiliary functions and using iteration methods associated with a nonlinear integral inequality, the estimate of upper bound for the lifespan is obtained.

Key words: Semilinear double-wave equation, Blow-up, Nonlinear memory term, Lifespan
