Discussion Overview

The discussion revolves around the relationship between two lines of equations in the context of covariant Maxwell equations, specifically questioning why the second line follows from the first as presented in an attachment.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant asks for clarification on the derivation of the second line from the first in the attachment.
  • Two participants assert that the two sides of the equation do not follow from one another due to differing free indices.
  • Another participant notes a potential swap of indices and a change in the order of partial derivatives in the second line.

Areas of Agreement / Disagreement

Participants generally disagree on the relationship between the two lines, with multiple competing views regarding the validity of the transition from the first to the second line.

Contextual Notes

The discussion highlights potential issues with index notation and the implications of swapping indices and derivatives, but does not resolve these concerns.

It doesn't. The two sides of the equation have different free indices.

thanx!
 
For some reason they have mad a swap ##\mu\leftrightarrow\nu## in the second line...and also switch the order of the partial derivatives.
