Hi, I've decided to learn GR myself recently since it's like the "sexy" side of physics. But I'm getting stuck with the tensors notations already. Maybe my math background is just not sufficient enough to do GR.(adsbygoogle = window.adsbygoogle || []).push({});

In general, how do I know that an object is tensorial; for example, objects like Ta|b-Tb|a or Ta||b - Tb||a (| for partial derivatives, || for covariant derivatives and Ta or Tb are just the covariant vector components.) Thanks.

Also, can anyone recommend some good intro books on tensors and differential geometry? Maybe I should learn those concepts before going into GR...
