Frame dragging and rotation

    Is there a simple mathematical relation between the speed at which the Earth spins and the magnitude of the frame-dragging effect?

    bodies angular momentum. Let

    [tex]\Delta \equiv r^2 - 2Mr + a^2[/tex]

    Let [tex]\omega[/tex] be the angular velocity of the dragging of the inertial frame. Then

    [tex]\omega = \frac{2Mra}{(r^2 + a^2)^2 - a^2 \Delta sin^2\theta}[/tex]
