Recently, this problem has been naturally formulated in the context of uniformly $h$-convex hypersurfaces in hyperbolic space by Espinar-G\\'alvez-Mira. Surprisingly, Espinar-G\\'alvez-Mira find that the Christoffel problem in hyperbolic space is essentially equivalent to the Nirenberg-Kazdan-Warner problem on prescribing scalar curvature on $\\mathbb{S}^n$. This equivalence opens a new door to study the Nirenberg-Kazdan-Warner problem. In this paper, we establish a existence of solutions to the Christoffel problem in hyperbolic space by proving a full rank theorem. As a corollary, a existence of solutions to the Nirenberg-Kazdan-Warner problem follows.", "revisions": [ { "version": "v1", "updated": "2024-06-12T12:21:48.000Z" } ], "analyses": { "keywords": [ "smooth solutions", "hyperbolic space", "nirenberg-kazdan-warner problem", "convex hypersurfaces", "full rank theorem" ], "note": { "typesetting": "TeX", "pages": 22, "language": "en", "license": "arXiv", "status": "editable" } } }
