An umbilic-free hypersurface in the unit sphere is called MSbius isoparametric if it satisfies two conditions, namely, it has vanishing MSbius form and has constant MSbius principal curvatures. In this paper, under th...
设 x:M→R^(n+1)是凸域ΩR^n 上的严格凸函数 x_(n+1)=f(x_1,…,x_n)定义的一个局部强凸超曲面.如果 f 是下面方程的解,则称 M 为α相对极值超曲面:△ρ=(2-nα)/2(‖▽ρ‖~2)/ρ,ρ:=(det((a^2f)/(ax_iax_j)))^(1/(n+2)).2007年,贾...

Given an immersed submanifold x : M^M → S^n in the unit sphere S^n without umbilics, a Blaschke eigenvalue of x is by definition an eigenvalue of the Blaschke tensor of x. x is called Blaschke isoparametric if its M...
