Ralph Sarkis (Aug 28 2023 at 19:28):@Jean-Baptiste Vienney and I are writing a paper on the split idempotents work started here. Since the mathematical content is not very deep or difficult, I am thinking it would be great to spend a lot of time on making the paper as accessible as possible with lots of explanations and examples. This makes me inclined to submit to TAC Expositions, but we are not completely sure what "exposition" means precisely.
The style of the only paper there is more didactic than what I am used to, so that is a good sign, but reading it superficially, it also seems to be about results that have already appeared in the literature. Does "expository" just mean written with more pedagogical considerations, or does it also mean that it should be about stuff already recognized and appreciated elsewhere?
Nathanael Arkor (Aug 28 2023 at 20:32):From the editorial policy:
Expositions in Theory and Applications of Categories ("TAC Expositions") is a special series specifically designed for publication of well-written and novel expository articles on topics of current research interest in the theory and/or applications of categories. While a TAC Exposition article need not include new results, it must be novel in either its arrangement or viewpoint, providing a new perspective or context for known results. Authors considering submitting an expository paper are advised to consult an editor on its suitability for TAC Expositions.
Mike Shulman (Aug 28 2023 at 21:36):However, that policy doesn't exactly address the question of whether a TAC Expositions article can include new results or whether it should be purely expository. I'm an editor of TAC and I don't think I know the answer to that question either.
John Baez (Aug 28 2023 at 22:33):I got the impression that there were so few Exposition articles that the norms for them hadn't solidified yet.
John Baez (Aug 28 2023 at 22:34):(Just one, I guess.)

The wording "need not include new results" suggests to me that it may include new results.
John Baez (Aug 29 2023 at 08:15):Or else they don't understand English grammar and they're trying to say it needs to not include new results. :upside_down:
John Baez (Aug 29 2023 at 08:15):Just kidding. I think you're right.
John Baez (Aug 29 2023 at 08:18):Another category theory journal that allows expository papers but does not have many yet is Compositionality. We are trying to figure out what kinds of expository papers we want - but not enough people are submitting them for us to have concrete examples to think about.
Ralph Sarkis (Aug 29 2023 at 08:28):Hmm that's interesting, I do prefer Compositionality's template over TAC's.
