History of Nonlinear Oscillations Theory in France (1880-1940)

Focusing on the French scientific contribution to nonlinear oscillations, this work critically examines key developments in the twentieth century, particularly between the World Wars. It highlights the significant roles of diverse French scholars and France's unique position in facilitating scientific communication. The discovery of Henri Poincaré's 1908 text reveals his early application of limit cycles to radio engineering, challenging previous historiography that credited Andronov. This study emphasizes the interplay between mathematical analysis and technology, showcasing France's vital contributions to the theory's evolution.
