@XanderHenderson As soon as I cast the last deletion vote on the question, one of the answers shows an undeletion vote. Out of curiosity: (1) How come such an undeletion vote could have been cast before the deletion took place? (2) If the answer gets 3 undeletion votes, will the question and the answer be undeleted?
Inspired by the Collatz Conjecture, I have explored a variant that introduces an additional element x, altering the operation for odd numbers and exploring convergence towards the numbers 36-18-9.
Proposition: We define the iterative function $f(n)$ for $n \in \mathbb{N}$ and a parameter $x \in \...
Both the $5x+1$ and $7x+1$ variant of the Collatz sequence are conjectured to have large number of divergent trajectory. Here, i combined the two. As always, when you encounter even $x$, you apply $x\rightarrow x/2$, but if you encounter odd $x$, you have the option of applying either $x \rightar...
@Jakobian It is no "stretch" by any means. Rather, as explained in the closing comment if follows immediately (and obviously) from the two linked basic results.
@Jakobian Why do you think it is good to let users repeat basic proofs ad infinitum? Allowing such destroys all hope of the site functioning efficiently as a repository of answers since it makes it difficult if not impossible for users to locate the "best" answers by search.
