| Apr 14, 2011 at 0:03 | comment | added | Dmitri Panov | Sorry, I don't understand what you mean by $K(p)\cdot\langle p,\nu(p)\rangle^{-4}$ . Is this correct that if a surface $S$ in $R^3$ is given as a graph of a function $z=f(x,y)$, then the centro-affine curvature is the determinant of the Hessian of $f$? | |

added convexity tag and a remark explaining its relevance
