    The connection between knot simplification and free groups is very fascinating even though it seems obvious when you think about it, thanks for sharing!

    Very interesting problem and a truly genial solution! Congratulations! But what about constructions, where the picture falls after k nails are removed? Do you have any ideas or insights how it can be done?

    • @stefanandmaths883
      @stefanandmaths883  2 роки тому +3

      Thanks! To answer your questions, I know how to solve the puzzle if we remove k nails. Initially, I wanted to present the solution in this video, but I thought that it would be too much - the video would have reached at least 40 minutes and too additional theory would have been needed. However, I am seriously thinking of posting a new video in which I explain the solution of this second generalization.

    I regret you did not make the return journey, showing what Brunnian links this polynomial solution yields.

      To visualise them better, I bought some rope and really tried to make some real “Borromean rings”, for example. See if it helps you too :)

    Maybe you could focus more on giving some intuition that showing hard to digest proofs. Thanks for the vid!

    9:15 -9:50 is so funny to me, you don't really explain anything, burp out a bunch of notation and just expect people to know what you mean yet proclaim how simple it is. up until that point the video was great and I enjoyed it, though whoever named them brunnian and borromean links should rot, they sound way too similar for something that is probably commonly taught in a large lecture halls.

      @@stefanandmaths883 I think that breaking mathematical subject matter into clear and simple and short terms is a great difficulty for mathematicians . They should work on that because It can be done . It just takes someone with that extra skillset , that "je ne sais quoi !" . Those that can master that should prove to be Great Teachers !

      @DemonixTB Thanks for your feedback! I tried to explain “superficially” what a free group means so that people who had not studied it before would get an idea of what I was doing. If I had explained rigorously what a Free Group means, I would have needed to talk about a lot of Group Theory and the video would have had 3 hours :). Anyway, thanks again for your feedback and I will try to explain the solutions better in the future videos.
