-
摘要: 研究了一类具有非线性边界流的多孔介质方程。利用能量函数研究了该模型解的爆破时间的下界估计,推广了已有研究结果。Abstract: This paper deals with a porous medium equation with nonlinear flux on the boundary .The lower bound the blow‐up time of solutions to the model is obtained by using energy functions .The results of this paper generalize the related results in early references .
