How does one derive the general form of the Riemann tensor components when it is defined with respect to the Levi-Civita connection?
I assumed it was just a "plug-in and play" situation, however I end up with extra terms that don't agree with the form I've looked up in a book. In a general coordinate frame it should be of the form [tex] R_{\kappa\lambda\mu\nu}\equiv g_{\kappa\zeta}R^{\zeta}_{\;\lambda\mu\nu}=\frac{1}{2}\left(\partial_{\mu}\partial_{\lambda}g_{\nu\kappa}-\partial_{\mu}\partial_{\kappa}g_{\nu\lambda}-\partial_{\nu}\partial_{\lambda}g_{\mu\kappa}+\partial_{\nu}\partial_{\kappa}g_{\mu\lambda}\right)+g_{\kappa\zeta}\left(\Gamma^{\zeta}_{\;\mu\eta}\Gamma^{\eta}_{\;\nu\lambda}-\Gamma^{\zeta}_{\;\nu\eta}\Gamma^{\eta}_{\;\mu\lambda}\right)[/tex]
However, when I naively calculate ##R_{\kappa\lambda\mu\nu}=g_{\kappa\zeta}\left[\partial_{\mu}\Gamma^{\zeta}_{\;\nu\lambda}-\partial_{\nu}\Gamma^{\zeta}_{\;\mu\lambda}+\Gamma^{\zeta}_{\;\mu\eta}\Gamma^{\eta}_{\;\nu\lambda}-\Gamma^{\zeta}_{\;\nu\eta}\Gamma^{\eta}_{\;\mu\lambda}\right]## using that [tex]\Gamma^{\lambda}_{\;\mu\nu}=\bigg\lbrace\matrix{\lambda \\ \mu\nu}\bigg\rbrace=\frac{1}{2}g^{\lambda\eta}\left(\partial_{\mu}g_{\nu\eta}+\partial_{\nu}g_{\eta\mu}-\partial_{\eta}g_{\mu\nu}\right)[/tex] I end up with the following extra contributions [tex]\frac{1}{2}g_{\kappa\zeta}\left(\partial_{\mu}g^{\zeta\eta}\right)\left(\partial_{\nu}g_{\lambda\eta}+\partial_{\lambda}g_{\eta\nu}-\partial_{\eta}g_{\nu\lambda}\right)-\frac{1}{2}g_{\kappa\zeta}\left(\partial_{\nu}g^{\zeta\eta}\right)\left(\partial_{\mu}g_{\lambda\eta}+\partial_{\lambda}g_{\eta\mu}-\partial_{\eta}g_{\mu\lambda}\right)[/tex] which I can't seem to make disappear! What am I doing wrong?
