Definition
Let $L / K$ be a field extension.
Let $S \subseteq L$ be a finite subset of $L$.
Let $\struct{S, \mathscr I}$ be the matroid induced by Algebraic Independence over $K$ on $S$.
From Matroid Induced by Algebraic Independence is Matroid, $\struct{S, \mathscr I}$ is a matroid.
Then any matroid isomorphic to $\struct{S, \mathscr I}$ is called an algebraic matroid.
