Some of important univalence criteria for a non-constant meromorphic function π(π§) on the unit disk π» involve its pre-Schwarzian or Schwarzian derivative. We consider an appropriate norm for the pre-Schwarzian derivative, and discuss the problem of finding the largest possible π β (0, 1) for which t
