Global existence and blow-up of solutions to a degenerate parabolic system with nonlocal sources and nonlocal boundaries.

This paper deals with a nonlinear degenerate parabolic system with nonlocal source and nonlocal boundaries. By super-solution, sub-solution and auxiliary functions, a criteria for nonnegative solution of global existence and blow-up in finite time is obtained for this degenerate nonlocal problem. Finally, the blow-up rates of blow-up solutions are also estimated. [ABSTRACT FROM AUTHOR]
