| Abstract: | Dealing with blow-up properties for a degenerate and singular parabolic system with nonlinear nonlocal sources subject to the homogeneous Dirichlet boundary conditions.The local existence of classical solution is established.Under appropriate hypotheses,the global existence and the finite time blow-up of positive solutions are obtained. |
