Rest of the fucking owl…
All maths papers are like this
Every Wikipedia page on a mathematical concept as well
Disciplines in mathematics assume you’re familiar with that discipline’s shorthand, constants and common forms. Also, you’re not expected to read them as you’re able to read a book. If it’s 100% your niche specialty then maybe you could, but spending and hour or two puzzling out a broad understanding of a paper is absolutely normal, even for math academics.
The square you root in the second equation should go over the both integrals, but that step is pointless anyways. Just by symmetryzing the integration boundaries it’s already a Gaussian integral, which is a standard integral
If this is indeed real, can somebody please point me to the paper/text? That introduction has piqued my curiosity and I wanna read the whole thing, even if the math might be incomprehensible.
Are we sure this book isn’t a shitpost?
This is absolutely taking the piss. “No calculus is required” is obviously not true when there’s, what, five integrals on the page?
