Calculating Riemann Curvature Tensor: Faster Methods?

Click For Summary
Calculating the Riemann Curvature Tensor using Christoffel Symbols in 3-dimensional Euclidean Space is noted as tedious and prone to errors. The discussion highlights the potential for simplification when using an orthonormal basis, where specific relationships between differentials can be established. It suggests that while faster methods may exist, they are not necessarily simpler. The equations can be simplified significantly by considering the Gauss curvature and the volume element of the metric. Overall, the conversation emphasizes the need for more efficient techniques in tensor calculations.

I've been trying to calculate the Riemann Curvature Tensor for a certain manifold in 3-dimensional Euclidean Space using Christoffel Symbols of the second kind, and so far everything has gone well however...

It is extremely tedious and takes a very long time; there is also a high probability of making silly mistakes (like misplacing a variable). Are there any faster methods (not necessarily simpler) or is there no other alternative?

The equations simplify with respect to an orthonormal basis.

For a surface, if dx and dy are a local orthonormal basis for the 1 forms, then

dx = w_{12}^dy and dy = -w_{12}^dx

dw_{12} = -KdV where K is the Gauss curvature and dV is the volume element of the metric.
