Abstract

In this paper, we study some topological structure of a compact domain in $\mathbb R^{n}$ in terms of the curvature conditions and develop a geometric inequality involving the volume and the integral of mean curvatures over the boundary of the compact domain.

Keywords: $C(o)$-compact domain, Morse theory, Euler characteristic, focal point, cell complex, homology sequence, integral of mean curvature
