Barkatou, Mohammed; Khatmi, Samira Symmetry result for some overdetermined value problems. (English) Zbl 1170.35011 ANZIAM J. 49, No. 4, 479-494 (2008). Authors’ abstract: The aim of this article is to prove a symmetry result for several overdetermined boundary value problems. For the two first problems, our method combines the maximum principle with the monotonicity of the mean curvature. For the others, we use essentially the compatibility condition of the Neumann problem.
