Abstract: | This paper deals with degenerate diffusion equations with nonlocal sources. The local existence of a classical solution is given. By making use of super- and sub-solution method we show that the solution exists globally or blows up in finite time under some conditions. Furthermore, the blowup rates of the blowup solution are derived. |
