| contents | This paper investigates an isoperimetric-type problem posed by L. A. Santaló, concerning convex surfaces in hyperbolic 3-space that minimize total mean curvature among all convex surfaces with fixed surface area. The problem aims to characterize the geometry of such minimizers and to determine the optimal form of a Minkowski type inequality in hyperbolic 3-space. In this work, we propose a conjectural description of the minimizers under certain regularity assumptions. We also construct a family of convex surfaces as potential candidates for minimizers and establish a property of singular points satisfied by any minimizer. |
