In this paper, we shall work with surfaces of constant mean curvature one in hyper-bolic 3-space. We abbreviate constant mean curvature one by CMC-1. These surfaces share many properties with minimal surfacesin Euclidean 3-space. A strikingresultis that these surfaces have a hyperbolic analogue of Weierstrass representation formula [2].Another important property is that the total curvature of CMC-1 surfaces is not necessarily an integral multiple of An, and does not generally satisfy Osserman inequality [4]. Let / : M2 ―>H3(-l) be a CMC-1 immersion. Then there exist a null holomorphic immersion F : M2 ― SL(2, C), such that / = F ■F*, where M2 is the universal cover of M2. By taking the inverse of the matrix F, we can construct a new CMC-1 surface f_x : M2 ―>H3(―l), callit the inverse surface (or dual surface [5]). Although the inverse surface is defined on the universal cover M2, its metric ds2_xis well defined on M2. So we have two metrics on M2, and they have the same completeness [6].Umehara and Yamada have shown that if the surface / : M2 ―>H3(― 1) is complete and of finitetotal curvature, then the following inequality holds
