Abstract:
In this note we investigate some basic properties of the level sets of functions which are homogeneous with respect to nonisotropic
dilations. In particular we obtain a formula for the volume of the level sets in terms of the area on the level surfaces.
We relate the results to some well known mean value formulas for solutions of PDE’s.
