Navier-Stokes equations: Unpredictability even without butterflies?


Abstract


Mathematically, the movement of a fluid is described with the so-called Navier-Stokes equations. In the spirit of Newtonian mechanics, these equations should determine the future motion of a fluid from its initial state. However, despite remarkable efforts in this direction over more than a century, this determinism has not yet been proved, or disproved, mathematically. This paper offers a general perspective on the Navier-Stokes equations, the fourth millennium problem.
