Title: Dominating subsets under projections
 
Abstract:
 
Abstract: Let $d$ be fixed and let $V$ be a $d$-dimensional subset of $R^n$.
We show that there is a subset $I$ of the $n$ coordinates $\{1,2,...,n\}$ of
cardinality $(1/2-o(1))n$ such that for every vector
$w=(w_1,...,w_n) \in V$ we have:
$\sum_{i \in I}|w_{i}| \leq \sum_{i \notin I}|w_{i}|$.
 
We will consider also the continuous version of this problem and related
geometric questions.
 
This is a joint work with Allan Pinkus.
