Local Aronson-Benilan Estimates for Porous Medium Equations under Ricci Flow
收藏 引用
Journal of Partial Differential Equations 2011年 第4期24卷 324-333页
作者: ZHU Xiaobao Institute of Mathematics Academy of Mathematics and Systems Sciences ChineseAcademy of Sciences Beijing 100190 China.
In this work we derive local gradient estimates of the Aronson-Benilan type for positive solutions of porous medium equations under Ricci flow with bounded Ricci curvature. As an application, we derive a harnack type ... 详细信息
