We prove that all the
derivatives of a D-solution (u,p) of the Navier–Stokes equations in a plane
neighborhood of infinity ∁CR0 decay more rapidly than |x|𝜖−1∕2 for every positive
𝜖. Moreover, we show that if the flux of u through the boundary of CR0
is zero, the second derivatives of p are summable over the complement of
CR0.
