Paul Pierre Lévy (15 September – 15 December )^[2] was a French mathematician who was active especially in probability theory, introducing fundamental concepts such as local time, stable distributions and characteristic functions. Lévy processes, Lévy flights, Lévy measures, Lévy's constant, the Lévy distribution, the Lévy area, the Lévy arcsine law, and the fractalLévy C curve are named after him.

Biography

[edit]

Lévy was born in Paris to a Jewish family which already included several mathematicians.^[3] His father Lucien Lévy was an examiner at the École Polytechnique. Lévy attended the École Polytechnique and published his first paper in , at the age of nineteen, while still an undergraduate, in which he introduced the Lévy–Steinitz theorem. His teacher and advisor was Jacques Hadamard. After graduation, he spent a year in military service and then studied for three years at the École des Mines, where he became a professor in ^[2]

Lévy, Paul Pierre (–)

Paul Lévy was born on 15 September in Paris. He studied mathematics at the prestigious École Polytechnique, publishing his first paper at age After graduation, Lévy spent a year in military service and then resumed his study of mathematics, first at École des Mines, and then the University of Paris, where he received the PhD degree in Lévy was appointed professor of mathematics at École des Mines in , and then professor of mathematics at École Polytechnique in , where he remained until his retirement in He died on 15 December in Paris.

Paul Lévy made fundamental contributions in many areas of probability and stochastic processes, particularly in martingales and Brownian motion. A number of theorems and constructs in probability are named for Lévy, including the Lévy metric, the Lévy continuity theorem, the Lévy zero-one law, and the Lévy distribution.
