Hi. Thank you for your recent edits. An automated process has detected that when you recently edited Model theory, you added a link pointing to the disambiguation page Formal theory. Such links are usually incorrect, since a disambiguation page is merely a list of unrelated topics with similar titles. (Read the FAQ • Join us at the DPL WikiProject.)

Would you want to collaborate on an ordinal collapsing function? I was thinking of creating thinning hierarchies consisting of iterated shrewdness diagonalized of degrees of unfoldability, which are in turn diagonalized by ethereal cardinals. If so, how would we collaborate? Should we use Google Docs? Binary198 ( talk) 17:30, 21 February 2022 (UTC)

A while back you added a proof to the article Well-ordering theorem that the axiom of choice implies the well-ordering theorem. Near the end of the proof there's a notation using angle brackets. Is that a standard notation for ordered set? It might be good to add a brief explanation or a link explaining that. Will Orrick ( talk) 18:30, 25 January 2024 (UTC)
