Possible Errors in Writing Christoffel Symbols with a Symmetric Metric

Click For Summary
SUMMARY

The discussion centers on the correct formulation of the Christoffel symbols \(\Gamma^{k}_{ij}\) in the context of a symmetric metric \(g_{ij}\). The equation \(\Gamma^{k}_{ij} = (1/2) g^{kp} (g_{ip,j} + g_{jp,i} - g_{ij,p})\) is established as the correct representation, while the alternative formulation \(\Gamma^{k}_{ij} = (1/2) g^{kp} (2g_{ip,j} + g_{ij,p})\) is deemed incorrect. The confusion arises from misapplying the symmetry of the metric and misunderstanding the derivatives of the metric components.

Homework Statement



¿Why [tex]\Gamma^{k}_{i j} = (1/2) g^{k p} (g_{i p ,j}+ g_{j p ,i}- g_{i j , p})[/tex] can't be writed like [tex]\Gamma^{k}_{i j} = (1/2) g^{k p} (2 g_{i p ,j}+g_{i j , p})[/tex]

if i can say that the metric is symmetric?

Homework Equations



That is the relevant equation

What makes you think that ##g_{ip},_j = g_{jp},_i## ? Certainly, ##g_{ij} = g_{ji}##, but that's not what you've got here.

Also what makes you think that ##g_{ij},_p = -g_{ji},_p##, or was that sign error just a typo?
