### Abstract

We study the comparison principle and interior Hölder continuity of viscosity solutions of F(x, u(x),Du(x),D^{2}u(x)) + H(x,Du(x))-f(x) = 0 in O, where F satisfies the standard "structure condition" and H has superlinear growth with respect to Du. Following Caffarelli, Crandall, Kocan and Świȩch [3], we first present the comparison principle between L^{p}-viscosity subsolution and L^{p}-strong supersolutions. We next show the interior Hölder continuity for L^{p}-viscosity solutions of the above equation. For this purpose, modifying some arguments in [1] by Caffarelli, we obtain the Harnack inequality for them when the growth order of H with respect to Du is less than 2.
