Small subset sums. Ambrus, Gergely


Consider a finite dimensional, real normed space. For a given set of vectors of norm at most 1, which sum to 0, we would like to select a k-element subset with small norm. We provide sharp estimates. We also prove consequences regarding Steinitz's theorem. This is a joint work with Imre Barany and Victor Grinberg.
