She is also remembered for her struggles against discrimination against women in the Italian university hiring system.[4] A street in Rome is named after her.
After finishing her studies, Nalli assisted Bagnera in Palermo in 1911 and then began working as a school teacher. She completed a habilitation thesis in 1914 on the theory of integrals, and continued to work on Fourier analysis and Dirichlet series for the next several years.[5]
Academic career
Nalli served as assistant to Giuseppe Bagnera at the University of Palermo from 1 April 1911 to 16 November 1911. She then taught at a number of secondary schools, first in the girls' school at Avellino, then in Trapani, and from 16 November 1912 in the girls' technical school in Palermo. During this time Nalli continued her research, completing her thesis "Esposizione e confronto critico delle diverse definizioni proposte per l'integrale definito di una funzione limitata o no",[2] a study of the theory of the integral based on recent work on the subject by Émile Borel, Henri LebesgueCharles de la Vallée Poussin, Giuseppe Vitali and Arnaud Denjoy.[5]
In 1921, Nalli became extraordinary professor at the University of Cagliari. She had been ranked second to Mauro Picone in the competition for the position, possibly in part because she was female, but Picone chose to stay at the University of Catania and become head of mathematics there, so the Cagliari position fell to Nalli. In 1923, she was listed first in a search for a position at the University of Pavia, but not offered the position. Finally, after similar mistreatment from several other universities, she moved to the University of Catania as a full professor in 1927. At around this time, perhaps encouraged by Tullio Levi-Civita, she switched her research focus from functional analysis to tensor calculus.[5]
Nalli died on 27 September 1964, in Catania. A street in Rome, the Via Pia Nalli,[8] is named after her.[5]
Selected works
Pia Nalli published 61 mathematical works, including the monograph (Nalli 1914) and a textbook.[9] Her "Selected works" (Nalli 1976) include this monograph plus eleven articles on topics mainly belonging to functional and mathematical analysis: the following list includes also her doctoral thesis (Nalli 1911) and other works on tensor calculus
