A unified treatment of boundary layer and lubrication approximations in viscous fluid mechanics


It is a matter of every day experience to find the boundary layer and lubrication approximations exposed as if they had nothing in common.
It is the aim of this note to show that, in fact, they come from the Navier-Stokes system and that they correspond to some distinguished limits of the Reynolds number.
