Abstract
In this paper we extend Caffarelli's result on interior -estimates for viscosity solutions of uniformly elliptic equations and prove -estimates at a flat boundary. Moreover we extend a result of A.~\'Swiech and prove -estimates at the boundary. Thereafter we combine these results and prove global -estimates for equations with dependence on and . Finally, we show that the previous estimates lead to an existence result for -strong solutions.}
