Abstract

In the present paper, we first establish and verify a new sharp hyperbolic version of the Michael-Simon inequality for mean curvatures in hyperbolic space Hn+1\mathbb{H}^{n+1} based on the locally constrained inverse curvature flow introduced by Brendle, Guan and Li, provided that MM is hh-convex and ff is a positive smooth function, where λ(r)=cosh\lambda^{'}(r)=\rm{cosh}rr. In particular, when ff is of constant, (0.1) coincides with the Minkowski type inequality stated by Brendle, Hung, and Wang. Further, we also establish and confirm a new sharp Michael-Simon inequality for the kk-th mean curvatures in Hn+1\mathbb{H}^{n+1} by virtue of the Brendle-Guan-Li's flow, provided that MM is hh-convex and Ω\Omega is the domain enclosed by MM. In particular, when ff is of constant and kk is odd, (0.2) is exactly the weighted Alexandrov-Fenchel inequalities proven by Hu, Li, and Wei.
