摘要: This paper deals with the properties of the solution to a class of nonlocal degenerate reaction-diffusion equation with nonlocal source, subject to the null Dirichlet boundary condition. We first give sufficient conditions for that the solution exists globally or blows up in the finite time. Then the blow-up time is also given. At last, we obtain a property differing from the local source which the blow-up set is the entire interval.

We first give sufficient conditions for that the solution exists globally or blows up in the finite time. Then the blow-up time is also given. At last, we obtain a property differing from the local source which the blow-up set is the entire interval.
