Vito Volterra (May 3rd 1860 with Ancone, in the Steps - October 11th 1940 with Rome) is a Mathématicien and Italian Physicien . He is especially known for his work on the equations intégro-differentials, the dislocation of the crystals, and in Dynamique of the populations. He was adverse solved with the Fascisme, not hesitating to give up the academic honors by political conviction.
Biography
Volterra was born in a poor family with Ancona (then attached to the states of the Pope). After studies to Florence, it enters to the Université of Pisa in 1878. It obtains its Doctorat in Physique in 1882, carried out under the direction of Enrico Betti. It is named professor in Mechanic with the Université of Pisa in 1883.It is interested as of this time in the functional equations, and in particular with the Operators intégro-differentials. He is regarded as one of the founders of the analyzes functional.
With died of Betti in 1883, he becomes professor of Mathematical physics, always with Pisa. It occupies then the pulpit of Mécanique to Turin, before being named with the pulpit of Mathematical physics with Rome in 1900.
During the unification of the Italy, he is a burning patriot and is named Senator Royaume of Italy in 1905. In the same time, it is interested in the phenomena of Dislocation crystal.
During the First World War, it joined the Italian air forces in the body of the engineers, and works with the technological improvement of the air war.
After the war, it turns to the application of mathematics to the Biologie, and in particular to the models of Dynamique of the populations. It is at the origin of the predatory model and preys (cf Equations of Lotka-Volterra).
In 1922, it is opposed to the mode Fasciste of Benito Mussolini and in 1931, it refuses to lend a Serment of allegiance. It must then resign of its university station, and leaves abroad. It returns to Rome right before its death.
Price and distinctions
Vito Volterra was elected with the Royal Society in 1910 and with the Royal Society off Edinburgh in 1913.
A Cratère of the Moon bears its name.
