- We say that a field K is antirational over its subfield k if it does not happen that there are a finite algebraic extension K′ of K, an intermediate field K′′ between k and K′, and an element t such that K′ = K′′(t) and t is transcendental over K′′. Namely, K is not antirational over k if there are such K′, K′′, and t.
