Plurisubharmonic functions and subellipticity of the dbar-Neumann problem on nonsmooth domains
arXiv:math/9612205
Abstract
We show subellipticity of the d-bar Neumann problem on domains with Lipschitz boundary in the presence of plurisubharmonic functions with Hessians of algebraic growth. In particular, a subelliptic estimate holds near a point where the boundary is piecewise smooth of finite type.
