The proof section is 3.5 pages. That's really pretty short, as far as modern math results go. I get your point, though.

The abstract is a one liner and the intro has in the first line a formula or two. No idea if this is the tone of math papers but I call this dense :)

Compared to some of the papers I've read recently, this is extremely elegant and succinct and doesn't just jam all the math in line by line.

Comparatively one of the papers I looked at the other day was something like 100 pages long with a ~30 page proof section with very little free whitespace packed full of complex mathematics.
