May 3, 2012 at 17:35 comment added Ronnie Brown I have described my search in 1965-74 for higher order Seifert-van Kampen theorems as: "An idea for a proof in search of a theorem." It took 9 years to find the gadgets to get a theorem. I think it is quite good to look at the work we do as a search for theorems. There is an apochryphal dedication of a PhD Thesis: "I am deeply grateful to Professor X, whose wrong conjectures and fallacious proofs, led me to the theorems he had overlooked." Sounds like excellent supervision!! It also leads to the question: What is a theorem?
