Let P k denote the set of equivalence classes of nonsingular pencils of Ž . quadratic forms of even order defined over a field k, char k / 2. Let F k denote the set of k-isomorphism classes of hyperelliptic function fields defined over k. We Ž . Ž . define a map ⌽: P k ª F k and determine precisely
