However, due to disputes with André Weil , he left the group.

In 1936 he published a book on game theory ( Sur la théorie mathématique des jeux de hasard et de réflexion ), to which one of his last works in 1968 was dedicated (on Nim games ). In 1935 he published a theory of differentiation in abstract measure spaces.

He became a professor in Besançon and from 1938 in Clermont-Ferrand. In 1941 he became a professor in Algiers . In 1959 he became a professor for numerical mathematics in Paris. At the Blaise Pascal Institute of the CNRS , he did pioneering work in the field of image recognition . 1960 until its reorganization in 1969 he was director of the institute as successor to Louis Couffignal.
