comment Boosts are non-unitary!
Hi, they're hard to type on keyboards but most web pages etc. run on Unicode system to encode the characters which allows all of the alphabets etc. of the world! There are ways to type characters on English keyboard, too. Alt with 0161 pressed, release alt, could work on your keyboard (0160 is capital s-caron) although it types something else on mine LOL.

Try copy-paste. Yes, in Czechia, we have a Czech keyboard where "š" appears instead of "3" which is obtained as shift-3 and # is elsewhere, or with right alt, and so on. In tex, it is "backslash v space {s}", $\v s$, for some reason, it isn't allowed here. You can add a Czech keyboard in MS Windows. I am myself using a modified Czech American Lumo keyboard, downloadable from motls.blogspot.com/2011/09/… - it's as American as you can get, gives Czech characters more or less at usual Czech places, and allows 100 other characters by easy combos

It's related but this question is about the relativistic case but the older debate - both question and answer - is fully about the non-relativistic Galilean case so it's not quite the same problem.

comment Source Theory - Alternative to QFT
It was a pleasure, and good luck becoming a source theory expert - it may be sort of cool if you can do it.

I hope so because Schwinger himself is one of the fathers of renormalization theory. But I haven't really learned renormalization in that way.

possible duplicate of Hilbert space of harmonic oscillator: Countable vs uncountable? - it is really a mega-duplicate, see also physics.stackexchange.com/questions/87476/… physics.stackexchange.com/questions/65457/… physics.stackexchange.com/questions/98455/…
