I need to find all the non-zero components of the Riemann Tensor in a two-dimensional geometry knowing that the only two non-zero components of the Christoffel symbols are:
$Gamma^x_xx=frac1x$ and $Gamma^y_yy=frac2y$
knowing that: $R^alpha_betagammadelta=partial_gamma Gamma^alpha_deltabeta-partial_delta Gamma^alpha_gammabeta+Gamma^epsilon_deltabetaGamma^alpha_gammaepsilon-Gamma^epsilon_gammabetaGamma^alpha_deltaepsilon$
The result I have obtained is that all the components of the Riemann curvature tensor are zero. Is this correct? If it is, what does it mean that all the components are zero?
Thanks!!!
