摘要
本文研究一类具有非线性边界项的多孔介质方程组.通过构造自相似上下解得到一种新的临界Fujita曲线,这种临界Fujita曲线与低阶项系数有很大关系.
The paper deals with the porous medium system with nonlinear boundary flux. By constructing selfsimilar supersolutions and subsolutions, we obtain the critical Fujita curve which is conjectured with the aid of some new re- sults. It shows that the coefficient of the lower order term is an important factor that determines the critical Fujita curve.
