First, it seems as if the article is in a refereed journal, and I don't know what that means. Second, the more I read about "uxp" in and of itself, the more I am sure it is just "linear" tetration (or what some other people call the "fractional part" extension of tetration). This is by no means new. If anything, the paper seems to focus on uniqueness theorems, so there might be something to be gained after all.
