Gradient estimates for porous medium and fast diffusion equations via FBSDE approach
Gradient estimates porous medium fast diffusion equations FBSDE approach Probability
2012/6/27
In this paper, we establish several gradient estimates for the positive solution of Porous Medium Equations (PMEs) and Fast Diffusion Equations (FDEs). Our proof is probabilistic and uses martingale t...
