One of the few things that continues to elude me is how the mus, nus, rhos, and sigmas work. Take for instance the calculation of the affine connection in the homework. How does that work. I was okay with g_ij, but the inclusion of the k and the other parameter (I will call it l) throws me. Which parameters are for theta and r, and which are for x and y? Also many of the references I found just use numbers for the metric locations. I am just a little confused on the actual details on how to do this as I have never seen any of this before. | One of the few things that continues to elude me is how the mus, nus, rhos, and sigmas work.

Changes to this page get sent to my e-mail inbox, so if you put something here it's likely to get my attention.
