  lol, although I might have to take some blame by putting a link in my comment to begin with. Note: Keep in mind that some folks publish on Arxiv because it is far easier than going through a traditional publication process. As such, you sometimes get not-as-polished works like this, although they might update the article to fix some of those references.
