摘要：
We study a singular or degenerate equation in non-divergence form modeled on the p-Laplacian, -vertical bar Du vertical bar(gamma) (Delta u + (p -2)Delta(N)(infinity)u) = f in Omega. We investigate local C-1,C-alpha regularity of viscosity solutions in the full range gamma > -1 and p > 1, and provide local W-2,W-2 estimates in the restricted cases where p is close to 2 and gamma is close to 0.
