What do you mean "apply it to Klein Gordon"? do you mean we assume that if psi satisfies KG then psi doesn't satisfy the conservation...

What's bad with energy being conserved? Was there an attempt to replace SR with GR in RQM? or is LQG such an attempt, i.e they don't use...

Don't we have already such a PDF? Absolute value squared of the wave function of a particle.

What attempts have been to resurrect RQM (in order to ditch the fields' notion)? Besides the appearance of negative energies (which I...

When you say that you use a Hilbert system without natural deduction, do you mean that you can't use rules that are specific to the...

In my derivation I forgot to mention that I use y+0=y; acknowledged we proved already x+(y+z)=(x+y)+z plug z=0, and get...

You want to use A4 to prove associativity of addition, so we have for z=1: (x+y)+1=x+(y+1) this is an instantiation of axiom A4. Now we...

You need to use induction on z and to invoke an instance of A4.

Speaking of Folland's books, they are notorious for typos. Here's the errata for his 1st edition of the QFT book.

Thanks.

You mean as vectors the states are independent of eachother (i.e one is not a linear combination of the other). Theoretically every...

I wonder a state which is in a superposition that should annihilate itself before the wave function collapses... Maybe this can also...

Well, I've got two books that treat QFT for the math-geared ahead (I double majored in maths and physics), they kind of old. There's...

Well being orthodox in Q theory interpretations means usually to adhere to Copenhagen interpretation, as far as I can tell.

Ouch. That paper is above my pay grade, Mitchell. I'm an amateur, an IT guy who's read a lot of old papers, not a mathematical...
