Resumen de Comparison Principles and Pointwise Estimates for Viscosity Solutions of Nonlinear Elliptic Equations.

Neil S. Trudinger

• We prove comparison principles for viscosity solutions of nonlinear second order, uniformly elliptic equations, which extend previous results of P. L. Lions, R. Jensen and H. Ishii. Some basic pointwise estimates for classical solutions are also extended to continuous viscosity solutions.
