What's relation between factorial and tensor components.?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between factorials and tensor components, particularly in the context of the Levi-Civita symbol and dual tensors. Participants seek clarification on the underlying logic and practical examples related to these concepts.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the relationship may involve permutation and combination techniques but expresses difficulty in understanding the logic behind the factorials associated with tensor components.
  • Another participant questions the clarity of the initial inquiry, indicating that more detail is needed to provide assistance.
  • A different participant notes that factorials appear in the context of dual tensors and Levi-Civita symbols, asking how these factorials are assigned.
  • One contribution states that the presence of factorials is an artifact of using summation conventions, specifically mentioning that the Levi-Civita tensor in N dimensions typically includes a factor of 1/N!.
  • This same participant also mentions that understanding the Levi-Civita tensor as representing the unit pseudoscalar in the space eliminates the necessity for factorials.

Areas of Agreement / Disagreement

Participants express varying degrees of understanding and clarity regarding the relationship between factorials and tensor components. There is no consensus on the explanations provided, and multiple viewpoints remain regarding the role of factorials in this context.

Contextual Notes

The discussion highlights potential limitations in the initial inquiry due to a lack of detail and clarity, which may affect the responses provided. The relationship between pseudo-tensors and tensor densities is also mentioned but not explored in depth.

maybe its simple permutation and combination technique... I ve tried to resolve it on my own but I couldn't...The textbook which I read simply mentions it to be obvious..can anyone please elucidate me the logic behind factorials of "independent components of tensor curl" and levi cita

Can anyone also explain the relation between pseudo-tensor and tensor density.?(with practical example hopefully)
 
Physics news on Phys.org
can anyone please help me
 
What specifically are you are asking? Your post doesn't provide enough detail.
 
In dual tensors,levi ceta symbols we have some factorials..how are they assigned.?
 
It's just an artifact of using summation conventions. Levi-Civita in N dimensions generally has 1/N! appear somewhere.

Realizing that the Levi-Civita tensor represents the unit pseudoscalar in the space obviates the need for factorials.
