It is prove that if p _c = p _1q _1 - (m - p _2)(n - q _2) < 0 every nonnegative solution is global, whereas if p _c > 0, there are solutions that blow-up ... 展开 This paper deals with a degenerate parabolic system with nonlocal sources. It is prove that if p _c = p _1q _1 - (m - p _2)(n - q _2) < 0 every nonnegative solution is global, whereas if p _c > 0, there are solutions that blow-up and others that are global. When p _c = 0, we show that if the domain is sufficiently small, every nonnegative solution is global while if the domain large enough that is, if it contains a sufficiently large ball, there is no global solution. 收起
