Abstract

We consider minimal closed hypersurfaces M4 subset S5(1) with constant scalar curvature. We prove that, if M4 is additionally a Willmore hypersurface, then it is isoparametric. This gives a positive answer to the question made by Chern about the pinching of the scalar curvature for closed minimal Willmore hypersurfaces in dimension 4.
