Analysis of PDEs 2022-01-07 v1

Abstract

In this paper, a new method is represented to investigate boundary W2,pW^{2,p} estimates for elliptic equations, which is, roughly speaking, to derive boundary W2,pW^{2,p} estimates from interior W2,pW^{2,p} estimates by Whitney decomposition. Using it, W2,pW^{2,p} estimates on C1,αC^{1,\alpha} domains are obtained for nondivergence form linear elliptic equations and further more, fully nonlinear elliptic equations are also considered.
