Dec 12, 2024 at 3:20 comment added Gerry Myerson Abstract of Hollom's paper (abridged): "A poset $P$ is said to satisfy the finite antichain condition, or FAC for short, if it has no infinite antichain. It was conjectured by Aharoni and Korman in 1992 that any FAC poset $P$ possesses a chain $C$ and a partition into antichains such that $C$ meets every antichain of the partition. Our main results are twofold. We provide a counterexample to the conjecture in full generality, but, despite this, we also prove that the conjecture does hold true for a broad class of posets...."
Dec 12, 2024 at 3:17 comment added Gerry Myerson I want to post another answer, but when I click on the link to do so, it takes me to the answer I posted a few days ago (about the Ankeny, Artin, Chowla conjecture). So I'll just leave a comment. Lawrence Hollom has found conditions for the Aharoni-Korman conjecture (aka the Fishbone conjecture) to hold, and has found a poset which doesn't satisfy these conditions and is a counterexample. Details at arxiv.org/abs/2411.16844 – Abstract next comment.

Nov 23, 2020 at 16:59 comment added Peter Shor @Alexander Chernov: So if disproved conjectures count, then Connes' embedding conjecture is false. But this one is possibly too famous to be an answer here.

Feb 3, 2019 at 8:59 comment added Tobias Kildetoft @KConrad That example was the first that came to mind when I saw this question, and I might write something about it if I get the time, as well as Soergel's conjecture whose proof provided many of the needed tools for the counter examples. The linked question also really could do with an updated answer now that a partial replacement for Lusztig's conjecture has been found, though the exact status for primes below $2h-2$ is still very uncertain.

Feb 3, 2019 at 4:30 comment added KConrad @PeterShor do you mean not worthy of being noted or noteworthy of being... knotted? Well anyway, you could ask a separate (not seperate) question. Maybe mathoverflow.net/questions/138310/… would be a good candidate for an answer to it.

Feb 3, 2019 at 2:06 comment added Peter Shor What about disproved conjectures—where people have found counterexamples? Are those not worthy of being noted?
