Levy, Beppo

Beppo Levy was born into the Jewish family of Giulio Giacomo Levy and Diamantina Puglieze ^[1] . He graduated from the University of Turin , which he graduated in 1896. In 1901, he became a professor at the Technical School in Piacenza, in 1906 at the University of Cagliari, from 1910 at the University of Parma, and since 1928 at the University of Bologna . In 1909, B. Levy entered into a marriage in which he had three children. In 1925 he signed the anti-fascist manifesto B. Croce . Since the 1920s, B. Levy has been actively collaborating with the Italian Mathematical Union , publishing its official scientific bulletin. In 1939, a scientist, due to his Jewish origin, was forced to emigrate from Nazi Italy to Argentina. Here, in 1939-1961, B. Levy is an honorary professor at the University of Rosario, in which he created the Mathematics Institute back in the 1920s. In Rosario, B. Levy, among other things, accepted the thesis of Pedro Elias Zadunaysky on the calculation of the orbits of the moons of Jupiter.

Since 1906, B. Levy has been carrying out important scientific work in the field of mathematical analysis, for example, on the topics of the Lebesgue integral (including this - Levy's theorem on monotonic convergence ). In 1906-1908 he wrote outstanding works on elliptic curves , which he made a presentation at the International Congress of Mathematicians in 1908. He carried out calculations to find restrictions on the number of torsion subgroups , which finally succeeded in only in the 1970s Barry Mazuru . He was one of the first scientists to formulate the axiom of the choice of set theory in 1902. He also made a great contribution (based on the work of his teacher Corrado Segre ) to the theory of resolving singularities algebraic surfaces (1897).

In 1956, B. Levy was awarded the prestigious Italian Feltrinelli Prize .

The younger brother of B. Levy, Eugenio Eliya Levy , who fell in 1917 during the battles of the First World War, was also a famous mathematician.
