Critical exponent for the global existence of solutions to a semilinear heat equation with degenerate coefficients
The authors investigate a non-homogeneous semilinear parabolic equation which has degenerate weights coeffients in two types. According to the models, they show the non-existence of nontrivial global-in-time solutions under the assumptions in Theorem 1.1, while they give also sufficient conditions for the existence of global in time solution (unique) in Theorem 1.2.
