Talk:Ψ(Ω ω)

Is there a difference between this ordinal and ψΩ 1 (Ωω)? --Ixfd64 (talk) 19:02, April 9, 2013 (UTC)


 * I would presume so, they look different :P nvm, I missed the capital psi FB100Z &bull; talk &bull; contribs 20:34, April 9, 2013 (UTC)


 * They are the same ordinal, using two different notations. I know it's confusing. I switched to ψ0(Ωω) because it was easier to type in the title. We can go with either one. Deedlit11 (talk) 05:39, April 10, 2013 (UTC)

Who can write an article about Buchholz hydras? the growth rate of this function is awesome! Konkhra (talk) 00:36, April 10, 2013 (UTC)


 * I've heard of them, but I have found no good explanations. FB100Z &bull; talk &bull; contribs 01:40, April 10, 2013 (UTC)


 * I can make article about hydra games, in which both Buchholz's and Kirby-Paris' one will be explained. LittlePeng9 (talk) 05:16, April 10, 2013 (UTC)
 * That would be cool! Konkhra (talk) 05:34, April 10, 2013 (UTC)

Wait, it is the ordinal measuring strength of \(\Pi_1^1\)-\(\text{CA}_0\), but in the article about TFB ordinal written the same. Are they equivalent? Ikosarakt1 (talk ^ contribs) 05:59, April 10, 2013 (UTC)

No, the other article is incorrect. I will fix it. Deedlit11 (talk) 10:42, April 10, 2013 (UTC)

At the very least, these are not absolute infinity. $Jiawhein$\(a\)\(l\)\(t\) 10:09, April 10, 2013 (UTC)

Sources? and put this to the transfinite template. $Jiawhein$\(a\)\(l\)\(t\) 08:41, April 23, 2013 (UTC)
