摘要
Under appropriate conditions on f(x, t), we prove the existence of viscosity solutions to Delta(infinity)u = f(x, u) that take prescribed continuous data on the boundary of bounded domains. As an application, singular boundary value problems are investigated. These problems are shown to admit viscosity solutions and their asymptotic behavior near the boundary is analyzed. Maximum and comparison principles are used as the main tools in these investigations.
