@qcd.qft: Quantum field theory path integral with wick contractions on a quantum electrodynamic vertex #fyp #quantumphysics #quantumelectrodynamics

Clive Dziwomore Engineer Clavo :

The final result may indeed be correct, but that alone does not establish the consistency of the derivation. In Grassmann calculus, fermionic functional derivatives are sensitive to left versus right derivative conventions, and the associated sign factors must remain consistent throughout. Likewise, the factors of (i) need to be tracked explicitly. If the intermediate expressions contain errors, the rigorous response is to identify the cancellation or convention that preserves the final result,, rather than simply asserting its correctness. I kindly and humbly request you to show the step where the apparent sign discrepancy is resolved?[Big LOL]

gadamn bro and i tought master degree is good but every kid knows qft ig (but fr good work)

You forgot an additional minus sign coming from the fermionic derivative ordering that isn't correctly written 1st page and a bit more mistakes regarding the "i" in the first page and a few more stuff gotten wrong but overall you have a pretty solid concept of what's going on despite the flaws in ur calculations and stuff good work

bro this is tik tok 🫩
