Abstract
In this talk, we investigate viscosity solutions for a class of strongly nonlinear PDEs, including the Monge-Ampère equation, the convex envelope problem and the infinity Laplace equation. We develop monotone two-scale methods and establish their convergence within the Barles-Souganidis framework. Subsequently, we derive pointwise error estimates for solutions with low regularity by leveraging the structures of the problems. Numerical experiments are also presented to validate our theories.
