**abstract:**
In papers 1 and 2, it is considered the interesting question of non decaying solutions to
the Navier-Stokes Cauchy problem in the two dimensional case. The existence concerns
regular solutions defined for all t > 0.
In paper 3, it is considered the Navier-Stokes initial boundary value problem in a
two dimensional exterior domain Ω under the assumption of an initial data u0 in BUC (Ω) with
\nabla u0 ∈ L∞(Ω). We establish global existence and uniqueness of regular solutions.
