摘要/Abstract

摘要：

The gradient blowup of the equation u_t = Δu + a(x)|∇u|_p + h(x), where p > 2, is studied. It is shown that the gradient blowup rate will never match that of the self-similar variables. The exact blowup rate for radial solutions is established under the assumptions on the initial data so that the solution is monotonically increasing in time.
