| Jan 2, 2020 at 5:13 | comment | added | Martin Sleziak | The tag (small-uncountable-cardinals) is now gone - I have replaced it by (cardinal-characteristics) in all remaining questions: chat.stackexchange.com/rooms/10243/conversation/… | |
| Aug 2, 2019 at 11:49 | comment | added | Martin Sleziak | The tag (cardinal-characteristics) was created in July 2019. I have pinged one of the moderators back then and once again today to ask what are the plans with the two tags. | |

| Mar 16, 2019 at 22:41 | comment | added | Taras Banakh | @YCor Oh sorry for this misprint. I had in mind "no". | |
| Mar 16, 2019 at 22:40 | comment | added | YCor | @TarasBanakh do you mean "because there is no such cardinals"? | |
| Mar 16, 2019 at 22:38 | comment | added | Taras Banakh | @YCor Yes, I think that that post (about MA) do not fit very well to "small-uncountable-cardinals" because there is such cardinals in this question. | |
| Mar 16, 2019 at 17:13 | comment | added | YCor | Andrés Caicedo has removed small-uncountable-cardinals from mathoverflow.net/questions/40686 "variants of Martin's axiom at $\omega_1$". I would like to know participants' opinion about this. | |

| Mar 12, 2019 at 21:17 | comment | added | YCor | @CarlMummert OK I see; however my belief is that it's not just a separate discussion, because the benefit of a tag depends on the closely related tags. | |
| Mar 12, 2019 at 21:14 | comment | added | Carl Mummert | @YCor: I'm sorry - I just meant it is another issue related to the topic here | |
| Mar 12, 2019 at 20:41 | comment | added | YCor | @CarlMummert please could you link to that separate question about infinite-combinatorics? | |
| Mar 12, 2019 at 17:52 | comment | added | Carl Mummert | @Taras Banakh - I would also include combinatorics on $\omega$, such as Hindman's theorem and Szemerédi's theorem, which have a different flavor from cardinal characteristics. | |

| Mar 12, 2019 at 16:37 | comment | added | Taras Banakh | "Infinite-combinatorics" would rather describe methods where "small-uncountable-cardinals" -- objects. | |
| Mar 12, 2019 at 16:30 | comment | added | Taras Banakh | Yes "infinite-combinatorics" is a broader field which (almost) swallows "small-uncountable-cardinals" and contains a lot of other things. For me "small-uncountable-cardinals" are synonyms to "cardinal characteristics of the continuum". | |
| Mar 12, 2019 at 15:13 | comment | added | Carl Mummert | There is a separate question about the infinite-combinatorics. I would be OK with this being a broad tag that covers both Ramsey-type infinite combinatorics along with set-theoretic combinatorics and cardinal invariants. There's no tag wiki at this point - do other people have thoughts on what this tag should cover? | |
| Mar 12, 2019 at 12:19 | comment | added | Taras Banakh | @MartinSleziak I have check for $\mathfrak b$, $\mathfrak p$, $\mathfrak d$, "cardinal characteristic of the continuus", indeed, there more-or-less 100 post mentioning these cardinal charactistics in the proper sense. 874 poset mention $\mathfrak p$ but many of them in the different sense (line prime ideals etc) | |
| Mar 12, 2019 at 12:16 | comment | added | Martin Sleziak | Since I see that you were criticized on the main site for bumping several old posts, I will add a link to this older discussion: Do we have an unofficial quota on how many old questions one should bump for minor edits in a single day? (Several of the questions linked there and questions tagged bumping are about similar problems.) Sorry for the digression - this is not directly related to the creation of the new tag. | |

| Mar 12, 2019 at 12:01 | comment | added | Martin Sleziak | @YCor To me a more reasonable estimate seems to be by checking the posts about specific cardinal, for example there are 22 questions in tag (set-theory) mentioning $\mathfrak p$, most of them use this symbol in the sense of cardinal $\mathfrak p$. (There are a few more links in the original post, perhaps I should have restricted them to questions.) | |

| Mar 12, 2019 at 11:49 | comment | added | Taras Banakh | @YCore To be precise, it shows up 4+4=8 results for "small uncountable cardinal" and "small uncountable cardinals", indeed many of those 100 results do not relate to small uncountable cardinals. | |
| Mar 12, 2019 at 11:46 | comment | added | YCor | "small uncountable cardinals" yields 100 answers when typed without quotation marks. This means questions in which each word occurs in the thread... The number of questions about small uncountable cardinals is smaller. | |
