Boundary regularity and non-transversal intersection for the fully nonlinear obstacle problem
arXiv:1709.06618 · doi:10.1002/cpa.21814
Abstract
In this paper non-transversal intersection of the free and fixed boundary is shown to hold in any dimension for obstacle problems generated by fully nonlinear uniformly elliptic operators. Moreover, regularity results of the free boundary are obtained and a classification of blow-up solutions is given.
