Poincare, Jules Henri

There are other types of attractors. In 1881, Jules Henri Poincare has shown that a wide class of two coupled nonlinear differential equations leads to the solutions that tend to a particular oscillatory behavior independently of the initial conditions (limit cycle). 

Jules Henri Poincare (1854-1912), French malhemalician and physicist and professor at the Sorbonne, made important contributions to the theory of differential equations, topology, celestial mechanics, probability theory, and the theory of functions. Known as the last universalist, Poincare was excellent in virtually all domains of his time. Maybe the exceptions were music and physical education, where he was scored as, average at best... 

The subject remained dormant until the late nineteenth century, when the French mathematician Jules Henri Poincare pursued a couple of lines of study that led to different branches of topology. He looked at the relationship between the algebraic properties of an object and its geometrical properties, which gave rise to geometrical topology. He also studied physical processes in which classical mechanics seemed to be unable to describe the results, giving rise to the field of nonlinear dynamics, one of the branches that contributed to the rise of chaos theory a hundred years later. 

Jules Henri Poincare became Professor of Mathematical Physics and Mechanics at the University of Paris in 1885. In 1887. two years before Becquerel, he was elected a member of the Academie des Sciences.
