Abstract:

Blow-up of solutions to a class of weakly coupled semilinear double-wave system with nonlinear memory terms is studied. By employing test functions and slicing methods, nonexistence of global solutions to the Cauchy problem for the semilinear double-wave system in the subcritical case is proved. Also, the upper bound estimate of the lifespan of solutions is obtained.

Key words:

nonlinear memory term; weakly coupled semilinear double-wave system; blow-up
