Hi! I am dealing with the propagation of electromagnetic emissions through the atmosphere. To quickly outline: Imagine some charge distribution flying at relativistic speeds and inducing a four-potential A. We define some retarded time at which the charges are at some positions, and calculate...

I noticed, I copied the Latex code and forgot to swap out the beta... the upper beta should be a nu. I think I see what you mean, can you tell me how to justify it properly? Something like symmetry between nu and mu because it's both times contracted with the momentum? Thank you a lot!

Hello everyone! It seems I can't solve this exercise and I don't know where I fail. By inserting the metric on the lefthand side of I. and employing the chain rule, the equation eventually reads (confirmed by my notes from the tutorial): $$m\frac{\mathrm{d}p_\delta}{\mathrm{d}t} =...
