| Abstract: | In this paper, we focus on the affine sphere theorem related to homogeneous function. Based on Hopf maximum principle, we obtain that the affine sphere theorem does hold for given elementary symmetric curvature problems under concavity conditions. In particular, it gives a new proof of Deicke''s theorem on homogeneous functions. |
