For a connectedn-dimensional compact smooth hypersurfaceMwithout boundary embedded in $${\mathbb {R}}^{n+1}$$ R n + 1 , a classical result of Aleksandrov shows that it must be a sphere if it has constant mean curvature. Li and Nirenberg studied a one-directional analog of this result: if every pair of points $$(x',a), (x',b)\in M$$ ( x ′ , a ) , ( x ′ , b ) ∈ M with $$a<b$$ a < b has ordered mean curvature $$H(x',b)\le H(x',a)$$ H ( x ′ , b ) ≤ H ( x ′ , a ) , thenMis symmetric about some hyperplane $$x_{n+1}=c$$ x n + 1 = c under some additional conditions. Their proof was done by the moving plane method and some variations of the Hopf Lemma. We obtain the symmetry ofMunder some weaker assumptions using a variational argument, giving a positive answer to the conjecture in [13].
