3. The Ricci curvature tensor depends on the Christoffel symbols. For simplicity, the Ricci curvature tensor can be written as Ruv = Rvu = 0 v - v + . then the above equation can take the form as R12 - R21 = 01 12+101 510 02 12. Find the Ricci curvature symbol R2 using all the possibilities. - op, if u = 1, v = 2 (20)
