Biography
Frattini entered the University of Rome in 1869, where he studied mathematics with Giuseppe Battaglini, Eugenio Beltrami, and Luigi Cremona, obtaining his Laurea in 1875.
In 1885 he published a paper where he defined a certain subgroup of a finite group. This subgroup, now known as the Frattini subgroup, is the subgroup generated by all the non-generators of the group . He showed that is nilpotent and, in so doing, developed a method of proof known today as Frattini's argument.[1]
Besides group theory, he also studied differential geometry and the analysis of second degree indeterminates. [2]
