In this manuscript, we give a new proof of strong minimality of certain automorphic functions, originally results of Freitag and Scanlon (2017), Casale, Freitag and Nagloo (2020), Blázquez-Sanz, Casale, Freitag and Nagloo (2020). Our proof is shorter and conceptually different than those presently in the literature.
Dans ce manuscrit, nous présentons une nouvelle preuve de la forte minimalité de certaines fonctions automorphes, résultats établis à l’origine par Freitag et Scanlon (2017), Casale, Freitag et Nagloo (2020), ainsi que Blázquez-Sanz, Casale, Freitag et Nagloo (2020). Notre preuve est plus courte et conceptuellement différente de celles qui figurent actuellement dans la littérature.
