 Some estimates for compact hypersurfaces in hyperbolic space Bull. Korean Math. Soc. 2005 Vol. 42, No. 1, 39-44 Published online March 1, 2005 Azam Etemad Isfahan University of Technology Abstract : Let $M$ be a compact hypersurface in hyperbolic space and let $A$ be the area of $M$ and $V$ be the volume of the compact domain bounded by $M$. In this paper, we find a lower bound for $\frac{A}{V}$ in two cases, $M$ has constant scalar curvature and $M$ has constant mean curvature.
