We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

On Rigidity of hypersurfaces with constant curvature functions in warped product manifolds
Jie Wu and Chao Xia
Abstract
In this paper, we first investigate several rigidity problems for hypersurfaces in the warped product manifolds with constant linear combinations of higher order mean curvatures as well as "weighted" mean curvatures, which extend the work of Brendle-Eichmair and Montiel considering constant mean curvature functions. Secondly, we obtain the rigidity results for hypersurfaces in the space forms with constant linear combinations of intrinsic Gauss-Bonnet curvatures Lk. To achieve this, we develop some new kind of Newton-Maclaurin type inequalities on Lk which may have independent interest.
