Query: Construction de nombres extr\'emaux pour le probl\`eme de
  l'approximation simultan\'ee d'un nombre et de son carr\'e   We consider the problem of simultaneous approximation to a number and to its
square in a general framework that encompasses imaginary quadratic number
fields and fields of rational functions in one variable. In this context, we
construct new extremal numbers.
