Tensor Calculus Questions: Christoffel, Riemann & Ricci Tensors

Click For Summary
SUMMARY

The forum discussion centers on Tensor Calculus, specifically addressing the calculation of Christoffel Symbols, Riemann, and Ricci Tensors. Users recommend the software Maxima and ctensor for tensor calculations, highlighting their effectiveness and free availability. The conversation also clarifies the distinctions between Euclidean and Riemannian metrics, emphasizing that a Euclidean metric is a special case of a Riemannian metric characterized by its Pythagorean form in orthonormal coordinates. Additionally, the discussion touches on the coordinate independence of metrics and the importance of understanding different coordinate systems in the context of Riemannian manifolds.

Both are excellent. You won't be disappointed. :smile:

Ha! Be forwarned and expect to be pumeled with questions. This could be tough with the both of us having the same texts. I hadn't thought of that until now. I'm still waiting for delivery.
