Question
Given a vector space E, let (u)iel be
any finite linearly independent family in E, where I = m, and let (vj)jes be any finite family
such that every u, is a linear combination of (vj)jes, where |J|= n. Then there exists a set
L and an injection p: L→ J (a relabeling function) such that LnI = 0, |L|=n-m, and
the families (u)ier U (Up())IEL and (vj)jes generate the same subspace of E. In particular,
m ≤n.
