only integers

The definition says: "If the previous term is even, the next term is one half of the previous term. If the previous term is odd, the next term is 3 times the previous term plus 1.". So, you can not choose non-integers for the Collatz conjecture and the sections Iterating on rationals with odd denominators, 2-adic extension and Iterating on real or complex numbers need to be removed. 94.31.89.138 (talk) 18:01, 20 August 2024 (UTC)[reply]

And the section talks about it being an extension of the map.Naraht (talk) 18:03, 23 September 2024 (UTC)[reply]

All of these sections define clearly and properly what they mean and are adequately sourced. —David Eppstein (talk) 18:39, 23 September 2024 (UTC)[reply]

Prime numbers

There is no section on how 3n+1 conjecture may do anything with prime numbers; could use one.

Example: proving 3n+1 conjecture means there is no infinite Nnext=(3n+1)/2 sequence of prime numbers that just won't stop appearing.

Seriously, proving 3N+1 is real means proving curious sequences like this one are impossible. 81.89.66.133 (talk) 08:06, 20 December 2024 (UTC)[reply]

Solution of Collatz Conjecture

If you want to see a solution for Collatz Conjecture, refer to Volume 13 Issue 1 2025, Global Scientific Journal, "Unveiling the mystery of the Collatz Conjecture" by Sandoval Amui. It just takes elementary arithmetic (Geometric progressions) 2804:9188:1:9FBB:64EC:C3BF:D452:DDC3 (talk) 00:01, 13 February 2025 (UTC)[reply]

The article uses the word "begin" in excess. Can we use alternative synonyms please. 204.48.78.190 (talk) 23:07, 10 March 2025 (UTC)[reply]

Not done The word "begin" appears zero times in the article ("beginning" twice). --JBL (talk) 23:45, 10 March 2025 (UTC)[reply]
