Perron's method for p-harmonious functions
We show that Perron's method produces continuous p-harmonious functions for 1<p<2. Such functions approximate p-harmonic functions and satisfy a functional equation involving a convex combination of the mean and median, generalizing the classical mean-value property of harmonic functions....

Summary: | We show that Perron's method produces continuous p-harmonious functions for 1<p<2. Such functions approximate p-harmonic functions and satisfy a functional equation involving a convex combination of the mean and median, generalizing the classical mean-value property of harmonic functions. Simple sufficient conditions for the existence of barriers are given. The p=1 situation, in which solutions to the Dirichlet problem may not be unique, is also considered. Finally, the relationship between 1-harmonious functions and functions satisfying a local median value property is discussed. |
