主要研究一类具非线性源的非散度型扩散方程的渐近性质.在研究非线性源指数的临界指标理论的同时,也讨论了解的不熄灭性.
This paper is concerned with a doubly degenerate parabolic equation in nondivergence form with nonlinear sources. It is shown that there is a critical value for the exponent of the nonlinear source. Also the non-extinction property of solutions is discussed.
