Calabi lectures edit
The 1994 lectures of Calabi at UPenn (the links to which were removed by the now-banned User:Mathsci on 18 January 2022) are, from what I can tell, still available at the Internet Archive's Wayback Machine: [1]. I currently don't yet know enough about the subject to justify re-adding them with the archive links, but since my previous attempt at pointing it out was left unanswered, I'm now pointing it out here, which, in hindsight, is probably what I should've done in the first place.
