Non-negative post-blow-up solutions of the quasilinear degenerate parabolic equation
in RN (or a bounded domain with Dirichlet boundary condition) are studied. Various sufficient conditions for complete blow-up of solutions are given.
This paper deals with the positive solution to the doubly degenerate equationwhere σ > 0, m > 1, β > m(1 + σ). We prove single-point blow-up for a large class of radial decreasing solutions. Furthermore, the upper and lower estimates of the blow-up solution near the single blow-up point are obtained.
