Zolar V 70 Posted August 26, 2018 (edited) Lemmas: Lemma 1: Let P be prime and P >2. The smallest natural number N > P to contain P as prime is 2P. Lemma 2: Any natural number N can be written as a sum of one of its primes. Case 1: N is prime \[N = \sum_{1}^{1} N \] Case 2: N is a composite \[ N = 2^q *P_1 *P_2 *..*P_i \] \[ N = \sum_{1}^{2^q *P_1 *P_2 *..*P_{i-1}}{P_i} \] Notice if q = 0 then N is odd, else N is even. Lemma 3: For a prime P >2 G(P) = P+1 and \[ P+1 = 2^r *q_1 *q_2 *..*q_n \] where \[ 2 \leq q_i < P \] for i = 1,2,3 ...n Lemma 4: For any natural number P >2 written as a sum of one of its primes P_i , then \[ m*G(\sum{P_i}) = G_1(P_i) + G_2(P_i) + G_3(P_i)+...+ G_m(P_i) \] notice each \[G_m(P_i) = P_i +1 \] . Since \[P_i +1 < 2p \] all of its primes are \[2 \leq q_i < P \] for i = 1,2,3..n Lemma 5: For any natural number P >2, a function \[H^k(m*G(\sum{P_i})) = 2^r \] Where k is the number of iterations of \[ m*G(\sum{P_i}) \] Edited August 26, 2018 by Zolar V 0 Share this post Link to post Share on other sites

Since we assume the function already exists, our purpose here is to elucidate that function and show how the Collatz function is a natural byproduct of it. Also it isn't "my" terminology, it is the terminology used by Collatz himself. If you notice Lemma 4, m*G(sum P_i) = 2k or written differently: Let K > 2 be an arbitrary natural number with P_i primes not necessarily distinct, and P be the highest element of the set P_i then K + i = 2r where each of 2r's primes are 2 \leq q_i < P Proof: \[ \sum_{1}^{2^r * P_1 *P_2 *..P_{i-1}} {P} + i = 2r \] \[ {P_1}_1 + {P_1}_2 +{P_1}_3 +... + {P_1}_i + 1_1 + 1_2 + 1_3 +... +1_i = 2r \] notice each P_1 has a corresponding 1, then \[ ({P_1}_1 + 1) + ({P_1}_2 + 1) + ({P_1}_3 + 1) + ({P_1}_4 + 1) + ... + ({P_1}_i + 1) = 2r \] since each P_1 is prime, it can also be written as 2k+1, so \[ (2k+1 + 1) + (2k+1 + 1) + (2k+1 + 1) + (2k+1 + 1) + ... + (2k+1+ 1) = 2r \] Clearly each element is 2k+2 = 2(k+1) = 2m , then \[ 2m + 2m + 2m +...+ 2m = 2r \] Notice each \[ {P_1}_i + 1 < 2p \] then \[ {P_1}_i +1 = 2^r * q_1 *q_2 *... *q_n \] where \[ 2 \leq q_i < {P_1} i = 1,2,3,4,...,n \] 0 Share this post Link to post Share on other sites

No, i'm saying adding 1 to any odd integer P results in a number who's prime factors are less than the the highest prime factor in P.

I haven't even explored the semi-primes as a distinct set, so I am unable to answer your question."My question is what way did you use the conjecture to solve the problem of factoring?" - I used the fundamental theorem of arithmetic to write an arbitrary number of prime factors to any natural number i needed. 6 minutes ago, wtf said: Why isn't Collatz a "natural byproduct" of f(x) = 2?

The existence of those functions doesn't negate the existence of my function, nor does it conclude the uniqueness to any such functions. I can change the wording if that pleases the masses.

(A short abstract) Again I am also an amateur mathematician but for your proof to work everyone must understand what you are attempting to show. I like to work with examples when trying to understand series. Don't worry I'm an amateur as well. Abstract: I am attempting to show a function G(p) = p+1 for primes, reduces the primes in it. Next, I am going to show how that function applies not just to primes, but to any natural number. Then as an extension I will show how repeated iterations of that function converge to a power of 2. Then I am attempting to show the Collatz conjecture's odd function is a natural byproduct of it, and of course the even Collatz function will naturally result in 1 after repeated iterations. Couple sentences longer, but those are the steps. Essentially the core concept is the addition of 1 to a prime number ultimately reduces the primes within it. That is the behavior I noticed in the odd Collatz function. I only need to prove it for primes since every other number that is not prime, is simply a product of primes. So by some rewrite or manipulation, it can be shown that the same concept still applies. Note: we are working with Natural numbers for the symbols and their powers. Prime reduction example: Primes: 5,7,11,13,17,97 5+1 = 6 ; 6 = 2*3 ; Where 2,3 <5 7+1 = 8; 8 = 2*2*2 ; Where 2 <7 11+1 =12; 12 = 2*2*3; Where 2,2,3 <11 ... 97+1= 98; 98= 2*7*7 ; where 2,7,7 <97 Let \( k \) be prime then \( k +1 = 2^r * P_1 * P_2 * P_3 *... * P_n \) Since \( k +1 < 2k \) , the prime product does not contain \( k \) and \( 2 \leq P_i < k \) for each \( i = 1,2,3,4...n-1, n \) Non Prime number extension example: Let \( j \) be a composite natural number then \( j = 2^r * q_1 * q_2 *q_3 *... * q_n \) primes not necessarily distinct, where \( q_n \geq q_{n-1} \geq ...\geq q_1 > 2 \) If \( j \) is odd then \( r=0 \). else \( j \) is even and \(r >0 \) So \[ j =2^r * q_1 * q_2 *q_3 *... * q_n = \sum_{1}^{ 2^r * q_1 * q_2 *q_3 *... * q_{n-1}} q_n \] then \[ j +1 =2^r * q_1 * q_2 *q_3 *... * q_n +1 = \sum_{1}^{ 2^r * q_1 * q_2 *q_3 *... * q_{n-1}}q_n +1 \] Notice \( q_n +1 < 2q_n\) then the primes in \(q_n +1 < q_n \) Let \( i = 2^r * q_1 * q_2 *q_3 *... * q_{n-1} \) then \[ j +i =2^r * q_1 * q_2 *q_3 *... * q_n + i = \sum_{1}^{ 2^r * q_1 * q_2 *q_3 *... * q_{n-1}} q_n +i = 2 S \] Where each prime in \( S \) is less than \( q_n \) By the first example, we show how adding 1 to a prime number creates a new number who's primes are less than the original prime. By the second example we show how we can still apply the same concept to any natural number. Then its just a matter of rewriting the odd Collatz function to look like our function and showing how they both do the same thing to the numbers.

Trurl 9 Posted August 31, 2018 Ok here is what I don’t yet understand. Try a series for 85. In your example you would multiply by 3 and add 1.

If x is even divide by 2 If x is odd multiple 3 add 1 gives you even so divide by 2 still even divide by 2 till equals 1 The conjecture shows a relationship in factors but does not show those factors.

But, I'm not trying to find out what the primes actually are. Instead I am trying to show how adding 1 to any prime results in a new number whose primes are less than the original prime. Applying that relationship to composite numbers is the tricky part. The relationship to composite numbers is where the iteration part of the collatz conjecture comes into play. since the iteration lets you add more than just 1 to a composite number. infact if you were to add that upper index of the sum to a prime number then you have added one to every prime number in that series. and each of those has the prime P +1 property 33 minutes ago, uncool said: But in that case - how does 7+1=8 matter to 3*5*7+1 = 106, which decomposes to 2*53 (the latter of which is a larger prime than any appearing in 3*5*7)? You are exactly correct in wondering and asserting this, but that is where the last equation comes into play. if you add 3*5 to 3*5*7 then each 7 has a corresponding 1. then the property of P+1 applies. Granted adding 3*5 hardly seems the most efficient route, but we don't particularly care about the most efficient route yet. We only care to show that every number will converge to 2 after some M iteration. note: 106 = 14*7 + 8 or if we maintain our notation \[ \sum_{1}^{14}{7} + (7+1) \] Edited August 31, 2018 by Zolar V 0 Share this post Link to post Share on other sites

Trurl 9 Posted September 3, 2018 Ok, I’m listening. Where does this go from here? This is how I understand you: Add 1 to a Prime number and it can be written as a power of 2. Since all Composite numbers factors are Prime numbers, those Prime factors added to 1 reduce to a power of 2. This will reduce to 1 and prove the conjecture. Your job is to prove this is possible. My question is how do you factor the Primes and apply the conjecture without changing the value of original number. By this I mean you factor the number into two Prime numbers and add 2 (+1 each Prime) to coverage to 1 and prove the conjecture. But at the same time you did not apply 3x +1 to the original value breaking the series. I am probably wrong again. I just don’t follow the modifications to the conjecture series. I’m am just making clear if I am following what you are doing. But if you explain this, I’m onboard. I am still looking at the original proof to make sure my question made sense. I am not completely sure of all the functions affecting x. But if the above question is confusing I will simply ask this: Are you breaking the rules of the conjecture by apply functions? 0 Share this post Link to post Share on other sites

I don't believe I am. What I believe I have done is break apart the conjecture into its pieces that cause it to function the way that it does. There seems to be a lot of lee-way in what you can do simply because of its iterative approach and that it is not given some limit on the iterations for the convergence. Quote "Add 1 to a Prime number and it can be written as a power of 2. Since all Composite numbers factors are Prime numbers, those Prime factors added to 1 reduce to a power of 2. This will reduce to 1 and prove the conjecture." - Exactly, you get what I am trying to do.

By this I mean you factor the number into two Prime numbers and add 2 (+1 each Prime) to coverage to 1 and prove the conjecture. But at the same time you did not apply 3x +1 to the original value breaking the series." - Here is where it gets a little murky. In the original proof, I did not flesh out the idea enough and it is clearly lacking in detail. Subsequent posts with WTF have allowed me to elucidate this part with greater clarity. Factoring the primes is a tricky way to do it, it seems. Something that should be explored in more detail. However let us think about a product of primes in a different way. Let us think about a product of primes be equivalent to a sum of one of its primes. Then we know how many 1's it takes to add 1 to each prime. Indeed we can add 1 simply by iterating the "Prime Reduction Function" on that sum of primes. That iteration is equivalent to the iterations of the Collatz function and since there isn't a limit on the number of iterations we are allowed to do then we can iterate or add any number of 1's it takes to every "fully saturated" sum of primes. Lets define "fully saturated": I mean a sum of primes where each prime within that sum has a 1 added to it. Or worded differently: every prime within the sum of primes has had the "Prime Reduction Function" applied to it 1 times. Let us use math symbols: Let \( N\) be a composite natural number and \( 2^r *P_1*P_2*...*P_k \) be its product of primes. where \( P_k \) is the largest prime, though not necessarily distinct. then \[ N = 2^r *P_1*P_2*...*P_k = \sum_{1}^{ 2^r *P_1*P_2*...*P_{k-1}} {P_k} \] let \(w = 2^r *P_1*P_2*...*P_{k-1} \) and \( H\) be an arbitrary function that applies our prime reduction function \(G(P) = P+1 \) exactly \( w \) times. for a fully saturated sum: \[ H( \sum_{1}^{ 2^r *P_1*P_2*...*P_{k-1}} {P_k}) = (P_k + 1)_1 + (P_k + 1)_2 +(P_k + 1)_3+ ...+(P_k + 1)_w = \sum_{1}^{ 2^r *P_1*P_2*...*P_{k-1}} {P_k} + w \] or if we use the second wording style: \[ G^w ( \sum_{1}^{ 2^r *P_1*P_2*...*P_{k-1}} {P_k}) = G(P_k)_1 + G(P_k)_2 + G(P_k)_3+... + G(P_k)_w \] Edited September 7, 2018 by Zolar V 0 Share this post Link to post Share on other sites
