New weighted Alexandrov-Fenchel type inequalities for hypersurfaces in hyperbolic space
In this paper, we obtain two monotonic quantities under the locally constrained inverse curvature flow. Using the monotonicity, a family of new weighted geometric inequalities for closed static-convex hypersurface in hyperbolic space is obtained, which implies that, among all closed static-convex hypersurfaces with fixed weighted k-th () mean curvature integral, the geodesic ball reaches the maximum value of l-th () quermassintegral. We also consider the case of and obtain a geometric inequality which is an improved version of Wei and Zhou's result in Wei and Zhou (2023) [24].
期刊介绍:
The Journal of Geometry and Physics is an International Journal in Mathematical Physics. The Journal stimulates the interaction between geometry and physics by publishing primary research, feature and review articles which are of common interest to practitioners in both fields.
The Journal of Geometry and Physics now also accepts Letters, allowing for rapid dissemination of outstanding results in the field of geometry and physics. Letters should not exceed a maximum of five printed journal pages (or contain a maximum of 5000 words) and should contain novel, cutting edge results that are of broad interest to the mathematical physics community. Only Letters which are expected to make a significant addition to the literature in the field will be considered.
