This study presents several weighted regularity criteria for axisymmetric solutions to the three-dimensional magnetohydrodynamic equations, which can effectively describe the relationships between velocity and vorticity components.
We show several weighted regularity criteria for the axisymmetric solutions to the three-dimensional magnetohydrodynamic equations, involving u(r), u(z); u(r), b(r), partial derivative(r)u(z), partial derivative(r)b(z), u(r), b(r), partial derivative(z)u(theta), partial derivative(z)b(theta); u(r), b(r), partial derivative(r)u(theta), partial derivative(r)b(theta); or omega(theta), where u(r), u(theta), u(z) are the angular, swirl and axial components of the velocity respectively and omega(theta) denotes the swirl component of the vorticity.
