the fact that is an example in which theNavier–Stokes equations have been shown to be
susceptible of improvement. Several alternatives to these equations are briefly mentioned in
order to give an idea of the importance that the problem of extending the Navier–Stokes
equations has these days. We focus our attention on the recent proposal of extension of the
Navier–Stokes equations given by Brenner. Our analysis considers the stationary case for …
