Improved H\"older regularity for strongly elliptic PDEs
Improved H\"older regularity for strongly elliptic PDEs
We establish surprising improved Schauder regularity properties for solutions to the Leray-Lions divergence type equation in the plane. The results are achieved by studying the nonlinear Beltrami equation and making use of special new relations between these two equations. In particular, we show that solutions to an autonomous Beltrami equation …
