Paul Georges Malliavin (born September 11, 1925 in Neuilly-sur-Seine , † June 3, 2010 in Paris ) was a French mathematician.

Malliavin received his doctorate in 1954 under Szolem Mandelbrojt at the University of Paris ( Sur quelques procédés d'extrapolation ). Since 1973 he has been a professor at the University of Pierre and Marie Curie .

Malliavin became famous for solving an important problem of harmonic analysis ( Impossibilité de la synthèse spectrale sur les groupes abéliens non compacts , 1959). The Malliavin calculus he founded from stochastic analysis has been increasingly used in financial mathematics since the 1990s and 2000s. Malliavin originally introduced it in 1978 to study the regularity of stochastic differential equations. With it, a stochastic differentiation could be introduced (the previously developed Ito calculus dealt with stochastic integrals ). He was also one of the founders of stochastic differential geometry, the theory of Brownian motion on Riemann manifolds (withJames Eells , Itō Kiyoshi , Paul-André Meyer ).

Malliavin was invited speaker at the International Congress of Mathematicians (ICM) in Stockholm in 1962 (Ensembles de resolution spectrale) and in Warsaw in 1983 (Analyze differential sur l'espace de Wiener). He was a member of the Académie des Sciences and the American Academy of Arts and Sciences .

His wife Marie-Paule Brameret was also a mathematician. She received her PhD in 1965 and was a professor at the University of Paris VI.
