Ordinary differential equations gave rise to different branches of mathematics: they stimulated the development of calculus by Newton, the invention of topology by Poincare and motivated the study of Lie groups. On the other hand, the theory of differential equations is the field of application of all the disciplines mentioned above, with complex analysis and algebraic geometry added to this list. The present course follows the modern exposition given by Arnold in his textbook, 1985. ...
