| Abstract: | The second boundary value problem for the fast diffusion system with inhomogeneous term was studied by the test function method and the comparison principle, obtaining its Fujita critical curve. We proved thenonexistence of the nontrivial nonnegative global solutions under the Fujita critical curve, and the existence of the nontrivial nonnegative global solutions above the Fujita critical curve. |
