摘要
We consider in this paper some class of perturbation for the semilinear wave equation with subcritical (in the conformal transform sense) power nonlinearity. We first derive a Lyapunov functional in similarity variables and then use it to derive the blow-up rate. Although the result is similar to the unperturbed case in its statements, this is not the case of our method, which is new to our knowledge.
