| Abstract: | This paper deals with a degenerate parabolic system with nonlocal sources.By making use of super and sub solution method we obtain the solution exists globally or blows up in finite time.When the solution blows up in finite time,we show that the blow.up set is the whole domain.Futhermore,we obtain the blow-up rate of the solution. |
