| Abstract: |
| In this paper, we deal with the large time behavior of solutions to the multidimensional Newtonian filtration equations coupled via the nonlinear boundary conditions. By constructing various kinds of upper and lower solutions, we obtain the critical global existence curve and the critical Fujita curve. |
| Key words: global existence blow up Newtonian filtration equation critical curves |
