Transformation law for Christoffel symbol of first kind

Click For Summary

Discussion Overview

The discussion revolves around the transformation law for the Christoffel symbol of the first kind, focusing on the challenges participants face in proving this law. The scope includes theoretical aspects of tensor calculus and differential geometry.

Discussion Character

  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant, Will, expresses difficulty in proving the transformation law for the Christoffel symbol of the first kind and notes that many resources only mention cyclic permutations and substitutions without detailed explanations.
  • Another participant, dextercioby, suggests providing results and calculations for the second kind symbols to assist Will in finding the first kind symbols.
  • Will acknowledges that the materials he has encountered may be outdated and indicates a preference for derivations that align with his current learning style.
  • Daniel challenges Will's assertion about the materials being old style, arguing that the approach taken in the resources is valid and emphasizes the manipulation of indices and derivatives to derive the transformation law directly from the covariant derivative of a covector.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best approach to prove the transformation law, with differing opinions on the validity of the resources and methods discussed.

Contextual Notes

Participants reference various styles of tensor calculus and express uncertainty regarding the derivation process, indicating a reliance on specific definitions and approaches that may not be universally accepted.

Hi,
I have met a problem, that is how to prove transformation law for Christoffel symbol of first kind. I have read books about that, but many of them just state: cyclic permutation of the 3 indices and substitution. When I tried to work out, I could not elimate some terms...
Can anyone show me how to prove it once.
Will.

By prove,u mean calculate it,right??I'll give u the results and the calculations for the second kind symbols and let u strive to find the first kind symbols.

Thx dextercioby,
I think ,what I have read, is a old style Tensor. So most books, I have read, derive the second kind transformation law from the first kind. Thank you very much for your help. It would be more happy to me if I can get some derives base on the style, what I am learning.

Will.

No,what u've read was a about 90% of a page from a pdf-format book on GR.That's why it used Greek suffixes.If it's old style,well,i doubt it,since he takes diff.geometry from zero,from the definition of a topological space.
I believe u can manipulate suffices,derivatives and other tensorial quantities so that u can get the first kind symbols' transformation law directly from the expression of a covariant derivative of a covector.

Daniel.
 
thanks .
