title says it all. I've heard these two phrases.(adsbygoogle = window.adsbygoogle || []).push({});

Lorentz invariant: Equation (Lagrangian, or ...?) takes same form under lorentz transforms.

Lorentz covariant: Equation is in covariant form.

I'm don't think I know what I mean when I say the latter. Can someone elucidate the difference between these two. Is there some necessary/sufficient condition that relates the two.

Thanks for your help!
