Abstract: In this paper, we take a direct method in calculus of variation to discuss some linear equation on Sn and get the existence and the uniqueness of its positive solution, by this method we give a proof for the Firey 2-sum Christoffel problem.

Key words: Christoffel problem, direct method, Firey 2-sum, Christoffel problem, direct method
