But the trouble with that is there is no Iain Davidson showing up as ever being a mathematician in the UK, or graduated with a math degree. So whether he is using a fake name also is an open question. LWalk, do you see the flaws of the below Iain Davidson offering. And Davidson misnumbered his offering with two steps numbered 3). His first big mistake is that his Lemma deletes the important characteristic that all Natural numbers are divisible by themselves. That mistake would be akin to me saying that a prime number is divisible by 1 but omitting the fact that it is divisible by itself. Davidson's half baked lemma in 2) is the fatal flaw for it should read "Every natural >1 is divisible by itself and by at least one prime divisor. So that when Davidson forms W+1, it is divisible by W+1 and divisible by 1 and hence by Davidson's step 1), the newly formed number W+1 is a prime natural number. So Davidson has no contradiction and must add on about three more steps in order to have a valid Indirect. Already, Davidson's offering is seven steps long and adding three more to make it a proof would be ten step proof. --- Iain Davidson offering which really has seven steps, not six --- > 1) A natural is prime if it has preceisly two distinct divisors > 2) Every natural >1 has at least one prime divisor > 3) GCD(m,m+1) = 1, for any natural m > 3) Assume pn is the last prime > 4) w = the product of all primes > 5) 3) => gcd(w,w+1) =1 => no prime divides w+1 > This contradicts 2) > 6) Therefore: Assumption 3 is false > - pn is not last prime LWalk, here is my proof: short form Indirect (1) definition of prime number (2) hypothetical assumption, assume the primes are finite and that the sequence list is 2,3, 5, 7, 11, . . , p_k (3) multiply the lot and add 1, calling it W+1 (4) W+1 is necessarily a new prime because of definition in (1) joining with the fact that division of W+1 by all the primes that exist in (2) leave a remainder (5) contradiction to (2) that p_k is the largest and last prime, for W +1 is now the largest prime (6) reverse supposition step (2) and primes are infinite Notice, LWalk it takes me six steps in all for a complete proof. It took me only two steps to conclude that W+1 was prime. It took Davidson seven steps which is an incomplete proof and which only establishes that W+1 is a prime number. Yet, LWalk and Davidson were thinking that W+1 was not a prime. Davidson's is not a proof but the mere establishing that W+1 is a prime number, and this is established because W+1 is divisible by itself and divisible by 1 so that W+1 has precisely two distinct divisors in Davidson's convoluted step 1) of the definition of prime. I have found always in life as in math, use the most direct definition, not some convoluted piece. So Davidson has no proof, but only a seven step argument that leads to the conclusion that W+1 is a prime number. And Davidson never admits that W+1 is a prime. And LWalk became interested in Davidson's argument because he proclaims that W+1 cannot be prime. And Davidson's last step which he misnumbered as 6) when it is 7) is utterly false given the prior six steps because Davidson never admits that W+1 is prime and so it cannot be a prime larger than pn; who knows what he was thinking. For anyone who cannot even give a accurate Lemma of all its parts, rather than deleting half the Lemma, we cannot expect to assemble a valid proof, nor understand his mistakes. So it takes Davidson seven steps to find out W+1 is a prime number, for which he insists is never a prime. LWalk, please reconsider your evaluation of Davidson's offering and criticism. He is messy, sloppy, posts only half of what a Lemma really is, and worst of all, lacking of any manners or politeness. Somewhere along the line, he never learned the basic core teaching that every human must have-- being courteous, being polite and full of good manners and cheer. Please reconsider your judgement, LWalk. I know Davidson can never admit wrong. But I expect it is easy for you, LWalk to admit to your mistake. LWalk, you do not want to be seen as endorsing the deletion or lopping off of a Lemma.

If the lemma is false state an n for which it is false.

Poor Archie, you really are completely clueless. Everyone knows that the trivial divisors of n are 1 and n. 1) n is divisible by 1 2) n is divisible by n So that when Davidson forms W+1, it is > divisible by W+1 and divisible by 1 and hence by Davidson's step 1), > the newly formed number W+1 is a prime > natural number. You have no idea what you are talking about. So Davidson has no contradiction Of course there is a contradiction. "Every n>1 has a prime divisor" and "w+1 has no prime divisors" cannot both be true. Maybe you simply don't understand what a contradiction is. In fact, I'm beginning to think that you have no idea what any mathematical term means and that you are incapable of understanding any mathematical concept. It is as if your mathematical outpourings were being produced by a computer that was running a simple generative grammar with a mathematical lexicon. At first glance, what you write looks like maths, but if you look at it again, it is merely gibberish. |
