Hello All, Sorry if my question seems to be elementary. I am trying to find out a little bit details of the Riemann metric tensor but not too much in details. I found out the metric (g11, g12, g13, g14......). It provides information on the manifold and those parameters have the information. Looking into the notation: I found that g00, g01 have certain partial derivatives. I mean to say what actually it is? What g11 and g12 have? Excuse me, if I am sounding too elementary. Thanks.
