Abstract
In this note, we prove two regularity theorems for solutions to the Navier-Stokes equations of an I.B.V.P. in exterior domains. Namely, we prove that the setS of the singular points of a solution, if not empty, has at most 1-Hausdorff measureH 1(S)=0. Moreover, the setS is enclosed in a sphere of rayR for anyt>0. These results are obtained as corollaries to the partial regularity results furnished in [2].
