is false. There are an infinite number of primes, but each of them is finite.
Also, there is a proof "Every Prime has a succinct certificate", by Vaughn
Pratt IIRC, which says that every prime can be proven so in a finite number
of steps/time. On Monday, November 03, 2003 10:32 PM 0500 Jud McCranie <j.mccranie@...> wrote:

Every prime also has a successor  there is no largest prime (whereas there IS a largest member of any finite set, for example there is a tallest person in the world, or a smallest planet in the solar system). However, since primes are defined as being a subset of the positive integers, there is no infinite prime.
Does that make sense, Roger?

unbounded but that doesn't mean that the size can be infinite. Every
particular integer/prime is finite. There are an infinite number of them.  At 12:43 PM 11/3/2003, Roger Bagula wrote:

you respond (concisely and politely please) to each of the
questions below.
First my thesis: infinite primes do not exist. The set of
primes is infinite (because it has cardinality aleph_0).
Consider carefully the difference between these two statements.
The first says that, because infinity is not an integer and primes
are integers, the concept "infinite prime" is meaningless. The
second says that the set of primes can be put in onetoone
correspondence with the set of integers >0.
Yuo do not seem to like the classical proof, so let's prove the
number of primes (i.e the cardinality of the set of primes) is
infinite by another approach.
Do you agree that the set of natural numbers is infinite?
That is, do you believe that given a particular integer N, we can
always find a larger integer M, no matter how large N may be?
Do you agree that, given N, the value M=N+1 is larger than N?
Again, if not the game is over because we are not talking about
mathematics as understood by almost all the world's mathematicians.
Do you agree that each and every integer N > 1 has a unique
factorization into primes?
I'm concerned only with which primes appear in the factorization,
not with the order in which they are given. Numerical order is
conventional but it really doesn't matter which order they are in
for the arguments below.
Next, I am going to define F_N, where N is an integer > 0, to be
the value 2^(2^N)+1, so F_1 has the value 5, F_2 has the value 17,
F_3 has the value 257, F_4 has the value 65537, and so on.
Do you agree that the set of all values F_N is infinite?
I claim it is because the N can take any integer value and each
value of N yields a value for F_N.
Do you agree that all the values for F_N are distinct?
I claim they are because 2^N is larger than N, and 2^(2^N) is
larger than 2^N. I therefore claim that each F_i is greater
than F_j whenever i>j.
Do you agree that (x+y)*(xy) = x^2  y^2?
Now, let's take a look at F_N  2. By definition of F_N, this
quantity is equal to 2^(2^N)  1. Note that 1 is a square (it is
1 squared and that 2^(2^N) is a square (it is 2^(2^(N1)) squared.)
So, do you agree that the following equation is correct?
F_N  2 = (2^(2^(N1)) + 1) * ( 2^(2^(N1))  1)
If so, you will readily conclude that the first term is just the
definition of F_(N1), and the second is just F_(N1)  2).
Now what does this tell us? (A rhetorical question, no need to
answer). It says that F_N  2 is a multiple of F_(N1). Of course,
we have to be careful. F_i is not defined if i is less than 1, so
we have to insist that N >= 2 in the above equation. So lets start
with N=2 and work our way up.
When N=2, F_2  2 = F_1 * (F_1  2).
This is easy to check:
F_2 is 17, F_1 is 5 and, indeed F_22 = 15 = 5*3 = F_1 * (F_1 2).
When N=3, F_3  2 = 255
= F_2 * (F_2  2)
= 17 * F_1 * (F_1  2)
= 17 * 5 * 3.
When N = 4, F_4  2 = 65535
= F_3 * (F_3  2)
= 257 * F_2 * (F_2  2)
= 257 * 17 * F_1 * (F_1  2)
= 257 * 17 * 5 * 3.
With me so far? Do you agree that we can continue this process
as far as we wish, because we can increase the value of N as far as
we wish?
If not, why not? I can try to make it clearer. If you do agree,
let's proceed.
I now claim that F_M has no prime factors in common with *any* F_N
for which N < M. The reasoning is that F_M  2 is a multiple of
all F_N for which N < M. Thus, any prime factor of F_N yields a
remainder of 2 when divided into F_M. All the F_N numbers are odd,
so we can discount the prime number 2 as being a factor of any of them.
Do you agree with this claim? If not, please explain what you think
is wrong with it.
Assuming you do agree, you will also agree that I have produced an
infinite set of numbers, none of which share a common prime factor.
The set of all F_N consists only of integers, so each and every one
has at least one prime factor, agreed?
But as the set of all F_N has cardinality aleph_0, the same as the
cardinality of the set of all integers >=1, AND every member of the
set of all F_N is an integer, AND every member of the set of all F_N
has at least one prime factor, AND no two members share any prime
factors, THEN the cardinality of the set of all prime factors of all
the members of the set of all F_N is itself aleph_0.
What does the above lengthy and pedantically stated sentence say
(another rhetorical question)? It says that we have constructed
a set of prime numbers which has cardinality aleph_0. That is,
we've found an infinite set of prime numbers. This, I claim, proves
my thesis given at the start of this article. Note I do *not* claim
that the set of primes I constructed contains all the primes. In fact,
we know for certain that it does not, and you should be able to prove
that, for instance, neither 2 nor 13 are members of the set.
Nonetheless, it is an infinite set.
Conclusion: the set of all primes is infinite (has cardinality
aleph_0) because at least one set which contains only primes itself
has cardinality aleph_0.

whether the number of primes is infinite or not, or (b) whether there are
some magical new numbers which you decide to call "infinite primes"?
You're quite correct of course, nothing in the posts has proved that no
infinite prime exists. In the case of (a), your attempts at proof have
been less than wonderful, and in the case of (b) none of us have any
idea what you mean by infinite prime.
I presume you're talking about whether there are infinitely many primes
or not, but you still seem to think that this would imply the existence
of "infinitely large primes". Not true. There would be *arbitrarily*
large primes, but they would always be finite. It's important to
understand this. Don't you have any number theory books you can look at
for this stuff? Try the first chapter of an introductory book...
As a little amusement, suppose that there were only finitely many
primes. Then the Euler product form of the zeta function would define an
entire function, thus making zeta(s) an entirely different animal.
Congratulations Roger, you would have answered the Riemann hypothesis, one
way or another.
Andy
PS "Modern school of thought"? You mean "Roger's school of thought"?
Small school then? I've just been trying to get the stuff on primes that calculation allows
and develop some "tricks" like:
I found a neat identity last night:
n!=Product[Prime[i],{i,1,PrimePi[n]}]*Product[Composite[i],{i,1,nPrimePi[n]}]
It allows one to compute the composites nearly directly in Mathematica:
(* Composite Product*)
p[n_]=n!/Product[Prime[i],{i,2,PrimePi[n]}]
digits=200
a0=Table[p[n]/p[n1],{n,2,digits}]
(* Composites by sorting out ones and two*)
Delete[Delete[Union[a0],1],1]
This function works much better than taking all the primes out of a list
of integers.
You can also get an higher number of primes by the Euclid proof
type integer factoring method.

[Nontext portions of this message have been removed]  The concept of "infinity"
is a Platonic ideal.
It can't be proven.
It is a limiting axiomatic definition (asymptotic).
So arguing if such an such types of infinity
exist , makes sense only if the limiting
case is assumed to exist in the first place.
Mathematics can be defined as two cases:
1) numbers where infinity is defined
2) numbers where no infinity is defined or definable as
being a nonoperational definition
( it crashes Mathematica, ha, ha... )
It is a philosophical distinction outside of normal mathematics.
Called since Gödel's time "metamathematical" statements/ arguments
after it was realized that a philosophical threshold
existed in certain kinds of proofs.
Statements like :
3) Aleph1=2^Aleph0
are outside of ordinary mathematics.
The algebra of transfinites is really a form of
metamathematics invented and outside ordinary mathematics.
It has it's own axiom system and rules.
The idea of an infinite prime would have to be
in this context and not in the context of finite primes at all.
A lot of people don't like it pointed out that irrational numbers depend on
a statement like 3)
being accepted as an axiomatic definition.
Like Euclid's product proof,
Cantor's proof of transfinites is also widely faulted in
modern mathematics.
The result is you get philosophical
and nearly religious in tone arguments
in mathematical forms like these egroups.
At first I didn't realize that it was that basic a
"postulate" , "axiom"
or
"definition", but it has become clear
that it is.
In modern science we are talking about a quantum
measure limit near 10^(33) cm, below which
what we know of as material and fields can't exist.
Much of current discussion on quantum gravity
comes down to "finite lattices" of spatial points.
So ideas at the integer level become very important.
And "infinities" become important on a philosophical
basis:
do they exist
or don't they?
Most of our calculations that make up
our ordinary lives don't require that any kind of infinity exists.
I don't know if any of this answers you list of questions or not.
I really don't like to get in such discussions,
since math people seem to ignore any philosophical issues by defining
them away.
Axioms and definitions are an answer to all their thinking problems?
As a physical scientist ( chemist, physical scientist)
I'm not bound by those rules in my thinking.
So I'm glad to say I can think of things outside of those rules.
I used to think that the topological approach was an answer
but that approach is bounded by set theory as well
and the logical problems of set theory seem to crop up
in it's proofs of infinite primes too?
The basic/ fundamental question seems to be :
Is any system that is based on axioms that resolve into
Platonic ideals, actually inductively defensible
as a form of knowledge?
In other words is science more fundamental
philosophically than mathematics at a metamathematical level?

The number 3^100 cannot be represented exactly in most versions of C,
and pi cannot be represented exactly in any language I know of without
taking shortcuts. Does this mean neither exists?

ZFC, though I wouldn't want to try from scratch).
Assume Aleph1=2^Aleph0. This implies that there is a mapping from the
Aleph1 real numbers onto the base 2 logarithms of the Aleph0 integers.
However, there are only countably many such logarithms (since there
are only countably many positive integers for them to be logarithms
of). This is a contradiction (and I'm sure it can be stated much more
formally). I would agree that the integers are a proper subset of the
base2 logs of integers, just as the primes, perfect squares, and
numbers evenly divisible by 100 are proper subsets of the integers.
However, all those sets are countably infinite.

the electromagnetic constant was 1/1000 of its present value, you
could, without starting from scratch? That's about the equivalent of
what you're asking us to do.
Regards,
Nathan  All that is fair enough, although if I was feeling cynical I'd read
that post as "I don't know what infinite primes are, but it sounds
nice".
Perhaps before we bother ourselves with what infinite primes might be,
we should instead concentrate our efforts on persuading the apparently
unpersuadeable that Euclid's proof is correct. I can understand how
arguments about Cantor's ideas can arise, since the whole concept of
uncountability is a sticky area to get used to. But Euclid's proof?
You seem either unwilling or unable to explain what your problem is
with this ridiculously simple method. The only post in which you've
tried to explain has (purposefully?) pushed the theory to a point
where an inexperienced amateur would worry that something was wrong.
Those of us with some experience pretty much instantly pointed out
just how rubbish your arguments were. Please explain!

to explain to you, and your recent message says
"Infinitely many primes is distinct from an Infinite Prime."  At 11:24 AM 11/4/2003, Roger Bagula wrote:

of us disagree with that. But you are assuming that an infinite number of
primes implies an "infinite prime", and your own recent message says that
isn't the case
"A semantic distinction needs to be made:
Infinitely many primes is distinct from an Infinite Prime.
Although one seems to imply the other,
they really involve two separate cases. "

No, it does not. Please post again, including my text and at
the appropriate point intersperse your answer to each specific
question that I asked.

of mathematical thinking. Rigorously correct logical arguments
are the building blocks placed on the foundations. If you wish to
be considered to be doing mathematics, please use clear and precise
logic.

participating in mathematics. Why, then, are you making so much
noise in an indubitably mathematical forum?
FWIW, my background is in the physical sciences. I have a BA in
chemistry from Oxford and my DPhil was for research in molecular
spectroscopy. I personally don't regard that as an obstacle to
contributing in a small way to a mathematical subject. I'm not
bound by the rules of mathematics any more than you are, but I
choose to follow them when communicating with mathematicians. If
you wish to converse with practitioners of other fields of study,
please do so but, please, do it in a relevant forum elsewhere and
use their rules to do so. Again, FWIW, I'm quite happy to talk
about quantum field theory or geometrodynamics, but not here.

A very good question and one well worth discussing, but not here.

It is not (IMO, the moderators may disagree) relevant to the
advertised aims of the forum.
