Abstract

For a smooth, closed and uniformly hh-convex hypersurface MM in Hn+1\mathbb{H}^{n+1}, the horospherical Gauss map G:MSnG: M \rightarrow \mathbb{S}^n is a diffeomorphism. We consider the problem of finding a smooth, closed and uniformly hh-convex hypersurface MHn+1M\subset \mathbb{H}^{n+1} whose kk-th shifted mean curvature H~k\widetilde{H}_{k} (1kn1\leq k\leq n) is prescribed as a positive function f~(x)\tilde{f}(x) defined on Sn\mathbb{S}^n, i.e. \begin{eqnarray*} \widetilde{H}_{k}(G^{-1}(x))=\tilde{f}(x). \end{eqnarray*} We can prove the existence of solution to this problem if the given function f~\tilde{f} is even. The similar problem has been considered by Guan-Guan for convex hypersurfaces in Euclidean space two decades ago.
