In this paper, we find two auxiliary functions and make use of the maximum principle to study the level sets of harmonic function defined on a convex ring with homogeneous Dirichlet boundary conditions in R2. In higher dimensions, we also have a similar result to Jagy’s. AMS Subject Classifications: 35B45, 35J92, 35B50 Chinese Library Classifications: O175.25
