Jules Henri Poincare (1854-1912)

Abstract Henri Poincare, Professor of Mathematics at the University of Paris from 1881 until his death, was the most prolific and influential mathematician of his generation. Although he was only 58 when he died, his technical articles fill eleven large volumes; he also published four volumes of philosophical essays on the foundations of mathematics and physics. His technical writings cover large tracts of pure and applied mathematics: algebraic topology, non-Euclidean geometry, Lie groups, number theory, differential equations, the theory of functions, algebraic geometry, mathematical physics, celestial mechanics.
