I would suspect that the @ comes from author email addresses. It's not entirely wrong to call that an operator. ;)

- mmooss 1y agoDo papers tend to have more email addresses or more plus signs? I'd expect the latter, by a lot.
- mkl 1y agoNo, the data (as described in So's thesis) was mathematical expressions extracted from TeX source code, so the surrounding text and email addresses etc. were ignored. Skimming through by eye I can't see @ in any of So's tables, and searching for the hex Unicode value the tables list for every other character yields no hits: @ is not in the tables. ∋ is there anomalously frequently, and @ is missing, so something seems to have gone wrong, probably at multiple stages in the pipeline.
