A Reilly approach to weighted curvature integral inequalities in hyperbolic space

Abstract

We establish a polarized weighted Reilly identity and an exact deficit decomposition for weighted curvature integrals $I_j=\int_ΣVE_j~\mathrm{d}μ$ in hyperbolic space, where $V=\cosh r$ and $E_j$ is the normalized $j$th mean curvature. For compact domains with smooth connected boundary, these yield $I_k^2\geq I_{k-1}I_{k+1}$ under intrinsic sub-staticity at $k=1$ and static convexity with $κ\inΓ_k\cap\overlineΓ_{k+1}$ for $2\leq k\leq n-1$, with equality precisely for geodesic balls. Under $h\geq0$ and $Vh-V_νg\geq0$, log-concavity and a Euclidean mixed-volume representation recover the centered-ball comparisons conjectured by Hu and Li \cite[Conjecture~1.1]{HuLi}, allowing the weight center to lie outside the domain. Equality in these comparisons holds precisely for balls centered at the weight center.
