Abstract
We consider the axisymmetric Navier–Stokes equations with non-zero swirl component. By invoking the Hardy–Sobolev interpolation inequality, Hardy inequality and the theory of $A_\beta \ (1 \lt \beta \lt \infty )$ weights, we establish regularity criteria involving $u^r$, $\omega ^z$ or $\omega ^\theta $ in some weighted Lebesgue spaces. This improves many previous results.
