On the other hand we do not have an extrinsic model for the hyperbolic ball in 3-space as well, and the explicit form for the metric of a minimal surface is given on the domain of the conformal parametrisation. Of course, one can ask which complete embedded examples without umbilics do exist. But even with the further constraint of finite total curvature we have at least one (class of) example(s). | |

But, they do tend to be immersed and therefore extrinsic in nature, so they are quite different than the kind of model that the Poincare disk is. Still, this is a nice class of examples. | |
