In his doctoral dissertation, and during the time from 1934 to 1939 when he was carrying out research in the Centre Nationale de la Recherche Scientifique, he studied topological properties of differential manifolds . In particular he described [1]:- ... the homology of classical types of homogeneous manifolds, such as Grassmannians, flag manifolds, Stiefel manifolds, and classical groups. He became a lecturer in the University of Strasbourg in 1939 but shortly after this he was back in the middle of the France/Germany conflict of his youth but this time on a quite different scale as the Germans invaded Alsace in 1940. During the German occupation of World War II, the University of Strasbourg's faculties were moved to Clermont Ferrand University in central France, then back to Strasbourg in 1945. Ehresmann followed the moves of the university then, in 1955, a chair of topology was specially created for him in the University of Paris. He held this chair until he retired in 1975. Although he was 70 years old when he retired, Ehresmann did not give up lecturing for at this time he moved to Amiens, where his second wife was a professor of mathematics, and he taught there.

We will celebrate the 100th anniversary of Charles Ehresmann's birthday. We plan to organize special sessions dedicated to Charles Ehresmann's life and work and the influence of his ideas on the modern mathematics. The main aim of the conference series is to present and discuss new results on geometry and topology of manifolds with the particular attention being paid to applications of algebraic methods. The topics usually discussed include: Lie groups (including infinite dimensional), Lie groupoids, Lie algebroids and their generalizations, Lie-Rinehart algebras, Characteristic classes, index theory, K-theory , Fredholm operators, Singular foliations, cohomology theories for foliated manifolds and their quotients, Symplectic, Poisson, Jacobi and special Riemannian manifolds, applications to mathematical physics.

Help Memory Evolutive Systems Ehresmann, Andree and Vanbremeersch, Jean-Paul Memory Evolutive Systems Full text available as: HTML Abstract Natural autonomous systems, such as biological, neural, social or cultural systems, are open, self-organized systems with a more or less large hierarchy of interacting complexity levels; they are able to memorize their experiences and to adapt to various conditions through a change of behavior. These last fifteen years, the Authors have developed a mathematical model for these systems, based on Category Theory. The aim of the paper is to give an overview of this model, called Memory Evolutive Systems.
