摘要
Abstract
In this paper,we derive a local gradient estimate of the Aronson-Benilan type with Laplace operator and drifting Laplace operator for positive solutions of porous medium equations posed on Riemainnian manifolds with bounded symmetric tensor by using Li-Yau method.These results extend Zhu Xiao-bao's and Deng Yi-hua's results.关键词
