| Sep 16, 2021 at 5:20 | comment | added | David Roberts♦ | @AaronBergman presumably that was the draft of the book now published? | |

| Feb 2, 2020 at 4:40 | comment | added | Maxis Jaisi | @BrendanGuilfoyle Okay, in any case there is at least another mathematician who is concerned about the disc embedding theorem, and has collected numerous resources and written (together with other topologists) a 200+ page book about it (you're likely to be aware). Link here: profmath.uqam.ca/~powell/freedmannotes.html | |

| Jan 30, 2020 at 8:03 | comment | added | Maxis Jaisi | @BrendanGuilfoyle Does Danny Calegari's set of notes resolve your worries? | |
| Mar 1, 2019 at 9:27 | comment | added | Lennart Meier | There is also a draft of a book project on this topic, which will hopefully appear this year (?) and is an extension of the lecture notes: profmath.uqam.ca/~powell/Freedman2017.pdf | |

| Feb 9, 2012 at 8:47 | comment | added | Brendan Guilfoyle | Thanks for the reference, I wasn't aware of it. However, it does not deal with the central question I'm interested in: the convergence conditions for infinite towers of Casson handles (or gropes). This paper gives a simplified proof that the original work extends from simply connected to other fundamental groups. It assumes what we'd like to see reproven. | |
| Feb 8, 2012 at 19:47 | comment | added | Igor Belegradek | @Brendan: I thought a more elementary argument is given in front.math.ucdavis.edu/0001.5063, which is a paper of Krushkal-Quinn "Subexponential groups in 4-manifold topology". I gather you are not satisfied with their approach, would you explain why not? | |

| Feb 6, 2012 at 17:18 | comment | added | Noah Snyder | I've rephrased this question to remove the (perhaps unintended) impression that the original proof may have issues. I do not think such innuendos are appropriate on MO. Feel free to revert if you disagree with me. | |
