Regularity and uniqueness of the first eigenfunction for singular fully non linear operators

Analysis of PDEs 2009-09-22 v1

Abstract

In this article we prove that solutions of singular fully nonlinear partial differential equations are C1,βC^{1,\beta}. We also prove the simplicity of the principal eigenvalues for the Dirichlet Problem associated to these operators using that regularity, a strict comparison principle and Sard's theorem.
