Leonida Tonelli (born April 19, 1885 in Gallipoli ( Lecce ), † March 12, 1946 in Pisa ) was an Italian mathematician , a student of Cesare Arzelà .
life and work
Tonelli studied in Bologna , where he received his diploma (Laurea) in 1907. In 1913 he was appointed professor at the University of Cagliari . Via the stations of Parma (appointment 1914) and Bologna (appointment 1922) he finally came to Pisa in 1930 , where he stayed until the end of his life (apart from a period from 1939 to 1942 at the University of Rome) and built up a leading school of analysts in Italy .
Tonelli's main field of work was analysis ; In particular, he dealt with the calculus of variations as one of his thematic focuses, but also with measurement and integration theory , trigonometric series and Fourier analysis . The Fubini-Tonelli theorem from integration theory is named after him.
He was a member of the Accademia dei Lincei and the Pontifical Academy of Sciences . In 1928 he gave a plenary lecture at the International Congress of Mathematicians in Bologna with the title Il contributo italiano alla teoria delle funzioni di variabili reali (German: The Italian contribution to the theory of the functions of real variables).
