Abstract: We study axisymmetric solutions to the Navier-Stokes equations in the whole three-dimensional space. We find conditions on the radial and angular components of the velocity field which are sufficient for proving the regularity of weak solutions. \endabstract

Keywords: axisymmetric flow, Navier-Stokes equations, regularity of systems of PDE's

Classification (MSC2000): 35Q35, 35J35
