Embedded hypersurfaces with constant $m^{\text{th}}$ mean curvature in a unit sphere

In this paper, we study $n$-dimensional hypersurfaces with constant $m^{\text{th}}$ mean curvature in a unit sphere $S^{n+1}(1)$ and construct many compact nontrivial embedded hypersurfaces with constant $m^{\text{th}}$ mean curvature $H_m>0$ in $S^{n+1}(1)$, for $1\le m\le n-1$. In particular, if the $4^{\text{th}}$ mean curvature $H_4$ takes value between $\dfrac{1}{(\tan \frac{\pi}{k})^4}$and$\dfrac{k^4-4}{n(n-4)}$foranyinteger$k\geq3$, then there exists an $n$-dimensional ($n\ge 5$) compact nontrivial embedded hypersurface with constant $H_4$ in $S^{n+1}(1)$.
