Definition:Vectorial Matroid

Definition

Let $V$ be a vector space.

Let $S$ be a finite subset of $V$.

Let $\struct{S, \mathscr I}$ be the matroid induced by linear independence in $V$ on $S$.

From Matroid Induced by Linear Independence in Vector Space is Matroid, $\struct{S, \mathscr I}$ is a matroid.

Then any matroid isomorphic to $\struct{S, \mathscr I}$ is called a vectorial matroid.
