Conjugate element (field theory)
（重定向自Conjugate roots）
In mathematics, in particular field theory, the conjugate elements of an algebraic element α, over a field extension L/K, are the roots of the minimal polynomial pK,α(x) of α over K. Conjugate elements are also called Galois conjugates, or simply conjugates. Normally α itself is included in the set of conjugates of α.
