Please help a newbie? I am having trouble with the following:(adsbygoogle = window.adsbygoogle || []).push({});

1) Lamda tensor metric conversion between local non-holonomic basis and global holonomic basis, how can you just "read off" the diagonal from the line element say in spherical coordinates and when do you choose the inverse metric (just take the inverse of each component of the diagonal?) when converting with either one-forms or vectors? pp 100 to 103.

2) Why did they choose to make the components of the tangent vector the partial diff operator making the vector an operator?

3) When calculating the Cartan coordinate free geodesic acceleration between two geodesics when the Lie bracket is zero (flat) how do you get the second total derivative with respect to tau as the product of tangent vector grad (tangent vector grad displacement vector). Do you take double Lie derivative on operators? pp 135

Thank you in advance. Mikah
