... Then there is a transcendence base B of K with A ⊂ B ⊂ S Proof. Since S is a set of generators of K, K/k(S ) is algebraic. Let M be the family of subsets A α of K with 1) A ⊂ A α ⊂ S 2) A α algebraically ... algebraic. Since K/k(S ) is algebraic, it follows that B satisfies the conditions of the theorem. The importance of the theorem is two fold; firstly that every se...
