What do you think? Granted you think at all.

i don't think they exist...:( sadly

Literally just integrate a function 5 times :3

oh, ok thanks!

They do in [math]\LaTeX[/math]. [eqn]\iiint[/eqn]

Oh shit, that wasn't 4...
[eqn]\iiiint[/eqn]

No. QFT doesn't exist
[math]Z = \int\mathcal{D}[\psi]\exp\left[\frac{i}{\hbar}\int d^{4}x \mathcal{L}\right][/math]

What do you mean by exist? You mean do they model real world phenomena? Then yes. You mean are they a calculatable thing? Then yes.

It's recently been proven that they indeed exist assuming the axiom of choice (Barnett 2013) but the proof is non-constructive and the brightest minds of mathematics have labored in futility to provide even one example.
