The qualitative theory of dynamical systems originated in Poincaré's work on celestial mechanics (Poincaré 1899), and specifically in a 270-page, prize-winning, and initially flawed paper (Poincaré 1890).
Who invented dynamical system?
Many people regard French mathematician Henri Poincaré as the founder of dynamical systems. Poincaré published two now classical monographs, "New Methods of Celestial Mechanics" (1892–1899) and "Lectures on Celestial Mechanics" (1905–1910).
What are dynamical systems used for?
Dynamical systems are mathematical objects used to model physical phenomena whose state (or instantaneous description) changes over time. These models are used in financial and economic forecasting, environmental modeling, medical diagnosis, industrial equipment diagnosis, and a host of other applications.
