BLOW-UP AND EXISTENCE FOR fast diffusion EQUATIONS WITH GENERAL NONLINEARITIES
收藏 引用
Acta Mathematicae Applicatae Sinica 1999年 第2期15卷 126-131页
作者: 穆春来 董光昌 Department of Mathematics Sichuan University Chengdu China Center for Mathematical Science Zhejiang University Hangzhou China
We give conditions on the function f so that the Cauchy problem to the fast diffusionequations with max has or no global solutions. Asa special case we recover the results to the case f(u) and prove that, if f(u) is ... 详细信息

Journal of Applied Mathematics and Physics 2016年 第5期4卷 903-913页
作者: Muhamediyeva Dildora CDSPHSC under TUIT Tashkent Uzbekistan
In this paper, we discussed population model of two competing populations with non-linear double diffusion and variable density which described by nonlinear system of competing individuals. We identify new properties,... 详细信息
