A Proof of the Collatz Conjecture
arxiv.orgFrom the abstract:
> In this paper, we show the new fixed point theorem in metric spaces. Furthermore, for this fixed point theorem, we apply to the Collatz conjecture.
That sounds like it's lacking some copy editing. So I'm not hopeful for the actual paper.
Also it doesn't look like this paper actually proves the Collatz Conjecture? It ends with:
> Unfortunately, the conditions of the theorem 2.3 are not satisfied in other cases.
> Furthermore, since N is discrete, Theorem 2.2 is sufficient without using Theorem 2.3, however, the conditions of the theorem 2.2 are also not satisfied.
And nothing more concrete.
Note this is version 2 of the Arxiv posting. The first version claims a proof of Collatz, which appears to be effectively withdrawn by the update.
Oh, that makes more sense. Thanks!
