For each hyperbolic metric $g$ on $M$ such that $\\dr M$ is smooth and strictly convex, the induced metric on $\\dr M$ has curvature $K>-1$, and each such metric on $\\dr M$ is obtained for a unique choice of $g$. A dual statement is that, for each $g$ as above, the third fundamental form of $\\dr M$ has curvature $K<1$, and its closed geodesics which are contractible in $M$ have length $L>2\\pi$. Conversely, any such metric on $\\dr M$ is obtained for a unique choice of $g$. We are interested here in the similar situation where $\\partial M$ is not smooth, but rather looks locally like an ideal polyhedron in $H^3$. We can give a fairly complete answer to the question on the third fundamental form -- which in this case concerns the dihedral angles -- and some partial results about the induced metric. This has some by-products, like an affine piecewise flat structure on the Teichmueller space of a surface with some marked points, or an extension of the Koebe circle packing theorem to many 3-manifolds with boundary.", "revisions": [ { "version": "v5", "updated": "2002-09-30T09:24:39.000Z" } ], "analyses": { "subjects": [ "53C45" ], "keywords": [ "hyperbolic manifolds", "polyhedral boundary", "third fundamental form", "unique choice", "convex co-compact hyperbolic metric" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2001math.....11136S" } } }
