Query: Blowup behavior of strongly perturbed wave equations   We study the blowup behavior of a class of strongly perturbed wave equations
with a focusing supercritical power nonlinearity in three spatial dimensions.
We show that the ODE blowup profile of the unperturbed equation still describes
the asymptotics of stable blowup. As a consequence, stable ODE-type blowup is
seen to be a universal phenomenon that exists in a large class of semilinear
wave equations.
