Français : Transformation du demi-plan de Poincaré en disque unité par une transformation conforme
English: Transformation of the Poincaré half-plane into a unit disc by a conformal transformation. The point I is variable on [Oy) and (Γ) is a circle going through B and whose center is I. The picture is the inverse of the half-plane y<0 with respect to the circle (Γ) I = (0,f(u)) for u= 1 to 50 with and a=1.1
