Global ๐^{2,๐} estimates for elliptic equations in the non-divergence form
Weifeng Qiu, Lan Tang ยท Proceedings of the American Mathematical Society ยท 2022
This paper is devoted to establishing global W 2 , p W^{2, p} estimate for strong solutions to the Dirichlet problem of uniformly elliptic equations in the non-divergence form where the domain is a Lipschitz polyhedra.
