Jul 30, 2017 at 20:02 | comment | added | Tobias Fritz | Something's wrong here, if I interpret 'the above fact does hold over any field' as claiming that for any subspace $V\subseteq F^n$, the set of supports of nonzero vectors in $V$ forms the dependent sets of a matroid. The obvious counterexample is the space of vectors of even parity in $\mathbb{F}_2^n$, for which the set of supports is not upwards closed. So what exactly is the correct statement? | |
