摘要：
In this paper, we will prove that any closed minimal Willmore hypersurface M-4 of S-5 with constant scalar curvature must be isoparametric. To be precise, M-4 is either an equatorial 4 sphere, a product of sphere S-2(root 2/2) x S-2(root 2/2) or a Cartan's minimal hypersurface. In particular, the value of the second fundamental form S can only be 0, 4, 12. This result strongly supports Chern's Conjecture. (C) 2017 Elsevier Inc. All rights reserved.
