Clearly the question is going to be closed and eventually deleted - so it does not matter much whether the typos were corrected or not. But I have to say that I liked the word "astronaunts". mathoverflow.net/posts/316015/revisions

Q: Yang-Mills theory with non-compact gauge groups G

wonderichPhysicists are familiar working with Yang-Mills theory with compact and semi-simple gauge groups $G$ (Lie groups). However, it is not entirely clear for Yang-Mills theory with non-compact or non-semi-simple gauge groups. One issue is that physical system governed by quantum theory and QFT, we ...

Are (feynman-integral) and (path-integral) two different things? (I just wonder whether we need two separate tags for them.) The tag (feynman-integral) already exists on the site. — Martin Sleziak 26 secs ago
Path integral formulation
The path integral formulation of quantum mechanics is a description of quantum theory that generalizes the action principle of classical mechanics. It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude. This formulation has proven crucial to the subsequent development of theoretical physics, because manifest Lorentz covariance (time and space components of quantities enter equations in the same way) is easier to achieve than in t...

I should probably have mentioned that wonderich created also the tag-excerpt and the tag-wiki for path-integral. The tag-info for feynman-integral is currently empty.

@Martin Sleziak, thanks, path integral is more general, I think we can merge (feynman-integral) into (path-integral). — wonderich 39 secs ago
@FrançoisG.Dorais Since you seem to be the moderator who most often deals with tag-related issues, maybe I could ask you what you think about the suggestion made above.
The issue I have with this suggestion is that path integral has several different meanings.
Of course, either me or the tag-creator can make a post on meta about this - if that's the preferred course of action.
