Query: The blow-up rate for strongly perturbed semilinear wave equations in the
  conformal case   We consider in this work some class of strongly perturbed for the semilinear
wave equation with conformal power nonlinearity. We obtain an optimal estimate
for a radial blow-up solution and we have also obtained two less stronger
estimates. These results are achieved in three-steps argument by the
construction of a Lyapunov functional in similarity variables and the Pohozaev
identity.
