COMPLETE HYPERSURFACES WITH LINEARLY RELATED HIGHER ORDER MEAN CURVATURES IN THE HYPERBOLIC SPACE
Published online by Cambridge University Press: 10 March 2025
Abstract
In this article, we study the behavior of complete two-sided hypersurfaces immersed in the hyperbolic space $\mathbb H^{n+1}$. Initially, we introduce the concept of the linearized curvature function
$\mathcal {F}_{r,s}$ of a two-sided hypersurface, its associated modified Newton transformation
$\mathcal {P}_{r,s}$ and its naturally attached differential operator
$\mathcal {L}_{r,s}$. Then, we obtain two formulas for differential operator
$\mathcal {L}_{r,s}$ acting on the height function of a two-sided hypersurface and, for the case where their support functions are related by a negative constant, we derive two new formulas for the Newton transformation
$P_{r}$ and the modified Newton transformation
$\mathcal {P}_{r,s}$ acting on a gradient of the height function. Finally, these formulas, jointly with suitable maximum principles, enable us to establish our rigidity and nonexistence results concerning complete two-sided hypersurfaces in
$\mathbb H^{n+1}$.
