Blowup properties for a class of nonlinear degenerate diffusion equation with nonlocal source 总被引:2,自引:0,他引:2
A nonlinear degenerate parabolic equation with nonlocal source was considered. It was shown that under certain assumptions the solution of the equation blows up in finite time and the set of blowup points is the whole region. The integral method is used to investigate the blowup properties of the solution. 相似文献
