Chern's Conjecture with Constant Cubic Trace

Huixin Tan, Zizhou Tang, Yuquan Xie +1

We prove that the values set of $S=|A|^2$ attained by closed embedded minimal hypersurfaces in $\mathbb S^{n+1}(1)$ with constant $S$ and constant \(f_3=\operatorname{tr}(A^3…

Isoparametric hypersurfaces in $S^{n} \times S^{m}$ and $S^{n} \times H^{m}$

Huixin Tan, Yuquan Xie, Wenjiao Yan

We prove that the angle function associated with the canonical product structure is constant for an isoparametric hypersurface in $S^{n} \times S^{m}$ , $\mathbb{S}…

Isoparametric hypersurfaces in $S^{n} \times R^{m}$ and $H^{n} \times R^{m}$

Huixin Tan, Yuquan Xie, Wenjiao Yan

We first show that every isoparametric hypersurface in $S^{n} \times R^{m}$ or $H^{n} \times R^{m}$ possesses a constant angle function with respe…
