Abstract: Let K be a global function field of characteristic 2. For each non-trivial place v of K, let K_v be the completion of K at v. We show that if two non-degenerate quadratic forms are similar over every K_v , then they are similar over K. This provides an analogue of the version for characteristic not 2 previously obtained by T.Ono.
