The authors present a survey on mathematical results and conjectures related to the concept of turbulence in viscous incompressible flow. First, they introduce the Navier-Stokes equations in abstract formulation and define and discuss the universal attractor X. Estimates of the fractal dimension of X, and the relation of these estimates to the Reynolds number are dealt with next. The final concept treated is the idea of an inertial manifold.
