Phragm\ue8n-Lindel\uf6f principles for nonlinear elliptic equations

This paper contains Phragm\ue8n-Lindel\uf6f type results for viscosity solutions of fully nonlinear second-order uniformly elliptic equations with superlinear gradient term in a wide class of unbounded domains. Under suitable assumptions on the coefficients, as classically, we show that the Maximum Principle holds in a generalized version of cylindrical and conical domains, resp., for subsolutions with exponential and polynomial growth at infinit
