Marc Yor
Marc Yor (24 July 1949 – 9 January 2014) was a French mathematician well known for his work on stochastic processes, especially properties of semimartingales, Brownian motion and other Lévy processes, the Bessel processes, and their applications to mathematical finance. Background
Yor was a professor at the Paris VI University in Paris, France, from 1981 until his death in 2014. He was a recipient of several awards, including the Humboldt Prize, the Montyon Prize, and was awarded the Ordre National du Merite by the French Republic. He was a member of the French Academy of Sciences. His students include such notable mathematicians as Jean-Francois Le Gall and Jean Bertoin. He died on 9 January 2014 at the age of 64.
