In this paper, we establish global Sobolev a priori estimates for Lp-viscosity solutions of fully nonlinear elliptic equations as follows: F(D2u,Du,u,x) = f(x)in Ωu(x) = φ(x) on ∂Ω by considering minimal integrability condition on the data, i.e. f Lp(Ω),φ W2,p(Ω) for n < p < ∞ and a regular domain Ω ⊂ Rn, and relaxed structural assumptions (weaker than convexity) on the governing operator. Our approach makes use of techniques from geometric tangential analysis, which consists in transporting "fine" regularity estimates from a limiting operator, the Recession profile, associated to F to the original operator via compactness methods. We devote special attention to the borderline case, i.e. when f p -BMO ⊇ L∞. In such a scenery, we show that solutions admit BMO type estimates for their second derivatives. © 2018 World Scientific Publishing Company.
