@Sergei Ivanov $\mathcal{K}/s^{n+1}$ is called centro-affine curvature. |

@Sergei Ivanov I believe if $E\subseteq\mathbb{R}^n$ is an ellipsoid centered at the origin then $\mathcal{K}/s^{n+1}$ is constant, where $\mathcal{K}$ is the Gauss curvature of $\partial K$ the boundary of $K$. |

@Carl Feynman The support function $h_A:\mathbb{R}^n\to\mathbb{R}$ of a non-empty closed convex set $A$ in $\mathbb{R}^n$ is given by :$ h_A(x)=\sup\{ x\cdot a: a\in A\},$ |

Lower bound on the curvature of the curves on $M$
I forgot this assumption: Curves should be intersection of a two plane and the manifold. |
