We prove the existence of a W<sup>2,p</sup>-viscosity solution to the above equation, which degenerates when the gradient of the solution vanishes.trueDirichlet boundary value problem | fully nonlinear degenerate elliptic equations | Pucci’s ex-tremal operator | viscosity solutionFully nonlinear degenerate equations with applications to Grad equationsArticlehttps://doi.org/10.14232/ejqtde.2024.1.26141738752024126arJournal1
