Optimal Weighted Smoothing and Asymptotics of Ancient Solutions for Fast Diffusion Equations
Beomjun Choi, Xiqin Jiang, Hua-Yang Wang +1
The Cauchy--Dirichlet problem for the fast diffusion equation on a smooth bounded domain admits a natural bound in the weighted space , where is the first Dirich…

A duality approach to gradient Hölder estimates for linear divergence form elliptic equations
Olli Saari, Yuanlin Sun, Hua-Yang Wang +1
We prove a sparse bound in the context of Schauder theory for divergence form elliptic partial differential equations. In addition, we show how an iteration argument inspired by sp…
