On finiteness of odd superperfect numbers
Journal de Théorie des Nombres de Bordeaux, Tome 32 (2020) no. 1, pp. 259-274.

On montre de nouveaux résultats sur l’équation σ(N)=aM, σ(M)=bN. On en déduit, comme corollaire, qu’il n’existe qu’un nombre fini de nombres impairs superparfaits ayant un nombre fixé de facteurs premiers distincts.

Some new results concerning the equation σ(N)=aM, σ(M)=bN are proved. As a corollary, there are only finitely many odd superperfect numbers with a fixed number of distinct prime factors.
