algebraically dependent
Let L be a field extension of a field K. Two elements α,β of L are algebraically dependent if there exists a non-zero polynomial f(x,y)∈K[x,y] such that f(α,β)=0. If no such polynomial exists, α and β are said to be algebraically independent.
More generally, elements α1,…,αn∈L are said to be algebraically dependent if there exists a non-zero polynomial f(x1,…,xn)∈K[x1,…,xn] such that f(α1,α2,…,αn)=0. If no such polynomial exists, the collection of α’s are said to be algebraically independent.
