Several versions of the anti-Hagedorn paper we discussed here, including some editions submitted to journals, as well as three more papers temporarily had the name of Joe Polchinski on the list of the authors. Euphemistically speaking, it was a typo. Joe Polchinski is not a co-author and does not believe that the paper is (or papers are) based on a rational idea.
The editors of journals and others are encouraged to learn that a combination of these two names (SC and JP) on a future paper will likely be another typo. More details here or here. I ask the commentators to avoid comments that could be inappropriate in this slightly sensitive context.
