Poincaré

Several members of the French Poincaré family have been successful in public and scientific life:

• Henri Poincaré (1854–1912), physicist, mathematician and philosopher of science
• Lucien Poincaré (1862–1920), physicist, brother of Raymond and cousin of Henri
• Raymond Poincaré (1860–1934), statesman, cousin of Henri

In physics and mathematics, a number of ideas are named after Henri Poincaré:

• Poincaré conjecture
• Poincaré recurrence
• Poincaré group, the group of isometries of Minkowski spacetime, named in honour of Henri Poincaré
• Poincaré inequality
• Poincaré map
• Poincaré model of non-Euclidean geometry
• Poincaré–Hopf theorem
• Poincaré duality
• Poincaré–Birkhoff–Witt theorem
• Hilbert–Poincaré series
• Poincaré metric
• Poincaré half-plane model
• Poincaré–Lindstedt method
