摘要

First, we establish some extended and refined results in the theory of viscosity solutions including a continuous dependence theorem, and a regularity result. Then, by investigating a certain type of partial differential equations, we expand the application of viscosity solutions to a broad range of higher-order partial differential equations. Finally, in the last section, we prove some corollaries that show the applicability of our results.
