In this paper, we refine some known regularity criteria of the 3D axisymmetric Navier-Stokes equations via establishing several new Hardy-Sobolev inequalities in mixed Lebesgue spaces and mixed Lorentz spaces. These inequalities cover many known corresponding results and are of independent interest. (c) 2023 Elsevier Inc. All rights reserved.
