Kiyoshi Itō

Kiyoshi Itō (伊藤清, Itō Kiyoshi ), born the September 7th 1915 with Hokusei-Chō in the Prefecture of Mie with the Japan, is a Japanese mathematician.

Biography

Kiyoshi Itō studied the Mathématiques at the Impériale university of Tōkyō. It was attracted there by the Calcul Probabilités.

It was interested in work of Kolmogorov and Paul Levy then later with the concept of regularization studied by Doob.

In 1940, it published One the probability distribution one has compact group , an important work in the evolution in this field.

Then it was interested in the processes Stochastique S and the Brownian Movement primarily after 1945.

In 1952, it introduced its theory of the Probabilité to the Université of Tōkyō.

Then he worked with the Cornell University and the Artuus University.

He bound mathematics to the forms of the beauty and had quoted in a text the music of Mozart, the Cathédrale of Cologne and said that these works had inspired the creation of its formulas:

“the music of Mozart, for example, impresses largely even those which do not know the theory of the music, the cathedral of Cologne subjugates also the spectators who do not know anything the Christian religion. The beauty of the mathematical structures, on the other hand, cannot be appreciated without including/understanding a whole of formulas which express the laws of logic. ”

It is this logic which it condensed in the Lemme of Itô.

He was prize winner of the Prix of Kyoto in 1998 and of the Prix Gauss in 2006.
