An eigenvalue problem for prescribed curvature equations

Abstract

We study an eigenvalue problem for prescribed ${\sigma }_k$-curvature equations of star-shaped, $k$-convex, closed hypersurfaces. We establish the existence of a unique eigenvalue and its associated hypersurface, which is also unique, provided that the given data is even. Moreover, we show that the hypersurface must be strictly convex. A crucial aspect of our proof involves deriving uniform estimates in $p$ for $L_p$-type prescribed curvature equations.
