*r-supported submanifolds in $R^n$.*

__Summary:__A submanifold $M \subset R^n$ is $r$-supported if for any $r$ points in $M$ there is a hyperplane, supporting $M$ and touching it at exactly these $r$ points. We prove that the minimal dimension $n=n(k,r)$ of the space $R^n$, containing a stably $r$-supported submanifold diffeomorphic to $R^k$, is asymptotically no less than $2kr-k$. - May 20
