"Ten Signs a Claimed Mathematical Breakthrough is Wrong"

(I haven't looked at the paper linked in the title.)

8 applies, at least.

It's like "you're interested in P = NP? I assume you've never heard of Turing machines, right?".

And 7, of course.

I’m not sure about that. I have never seen the notation Z_2 being used for the Gaussian integers, for example. Their notation is not quite standard and this is often a bad sign. Also the abstract on arxiv is full of latex commands…

> I have never seen the notation Z_2 being used for the Gaussian integers

For some reason, my brain totally slipped over that when skimming the abstract. I was like “Gaussian integers are a real thing, ℤ₂ is a real thing, okay, cool”.

Just the citations alone (or rather the lack thereof) are enough to put this in the crank bucket.
