Theorems that impeded progress


How to unify various reconstruction theorems (Gabriel-Rosenberg, Tannaka,Balmers)Theorems first published in textbooks?Theorems that are 'obvious' but hard to proveAn undergraduate's guide to the foundational theorems of logicProofs that inspire and teachExamples of major theorems with very hard proofs that have NOT dramatically improved over timeHistory of preservation theorems in forcing theoryAre there any Algebraic Geometry Theorems that were proved using Combinatorics?Did Euler prove theorems by example?Theorems demoted back to conjectures

It may be that certain theorems, when proved true, counterintuitively retard
progress in certain domains. Lloyd Trefethen provides two examples:




  • Faber's Theorem on polynomial interpolation

  • Squire's Theorem on hydrodynamic instability



Trefethen, Lloyd N. "Inverse Yogiisms." Notices of the American Mathematical Society 63, no. 11 (2016).
Also: The Best Writing on Mathematics 2017 6 (2017): 28.
Google books link.




In my own experience, I have witnessed the several negative-results theorems in




Marvin Minsky and Seymour A. Papert.
Perceptrons: An Introduction to Computational Geometry , 1969.
MIT Press.




impede progress in neural-net research for more than a decade.1




Q. What are other examples of theorems whose (correct) proofs (possibly temporarily)
suppressed research advancement in mathematical subfields?

    I remember reading, I believe in some other MO post, about how whereas Donaldson's work on smooth 4 manifolds launched a vibrant program of research with invariants coming from physics, Freedman's contemporaneous work on topological 4 manifolds essentially ended the study of topological 4 manifolds. But maybe that's not what you mean by "impeded progress"

    @SamHopkins: I am seeking more misleading impeding, as opposed to closing off a line of investigation. Certainly when a line has terminated, that's it. But there are also misleading endings, which are not terminations afterall.

I don't know the history, but I've heard it said that the realization that higher homotopy groups are abelian lead to people thinking the notion was useless for some time.
