I have a really weird #ICanHazPDF request. I remember a #MathOverflow question about the classification of #manifolds in which a paper (apparently unpublished) was linked from the author's website. I think it was by either Manolescu or Nicolaescu and it was a very nice, short survey of the current state of the classification. I thought I had a copy of this, but I can't find it or the original MathOverflow question. I've tried DuckDuckGo, Yandex, Google, and Bing to no avail. It's not this (https://pi.math.cornell.edu/~hatcher/Papers/3Msurvey.pdf) by Allen Hatcher. Did I hallucinate this survey article?
@caten This question? https://mathoverflow.net/q/264330/1345
Manolescu also has a survey from his ICM talk. https://arxiv.org/abs/1803.09870
@Ianagol I don't think so. I am familiar with this question and the linked papers. I really hope I'm not just misremembering, but I feel like there was a survey covering the classification of n-manifolds in general, including the cases where they can't be triangulated.
