TY - JOUR T1 - Degenerate Nonlinear Boundary Value Problems for Fully Nonlinear Elliptic Equations of Second Order AU - Lee Jiunjie JO - Journal of Partial Differential Equations VL - 4 SP - 66 EP - 86 PY - 1991 DA - 1991/04 SN - 4 DO - http://doi.org/ UR - https://global-sci.org/intro/article_detail/jpde/5784.html KW - Degenerate KW - nonlinear KW - estimate KW - elliptic equation AB - In this paper, we will consider the degenerate nonlinear boundary value problems for nonlinear elliptic equations. We extend Lieberman & Trudinger's results from nondegenerate oblique derivative boundary values to degenerate boundary values.
