Beal’s Conjecture, Fermat’s Last Theorem, Riemann Hypothesis

1. A Solution to Beal’s Conjecture

Beal’s conjecture states if where are positive integers, then have a common prime factor.

Since it is a conjecture it should either be proved or disproved so that we have to find simple way to handle it. In the search of a solution to the open problem after many trial and errors we decided to tackle it in the following way. Take

where are positive integers then

since is a

positive integer the square coefficient factors appearing in the left hand side of and cannot be fractions any more so that B and C must be divisible by A. Under the present circumstances either or must have A as common factor. That is the general proof that could be developed and we have to come up with numerical solutions & in its search it is possible to give a simple example. Take

the lowest prime number and 1 is not a prime number. So, is a solution. Further and in general for all and so on & 2 must be a pri- me factor conjectured by Beal. The example suggested is within the theory formulated.

Further satisfy Beal’s Conjecture. If we generalize it in this case prime factor is 3, countably infinite number of examples are satisfying the Beal’s Conjecture a different example. The series that we have introduced before is

not satisfying Beal’s Conjecture,

all, the entire set of countably infinite number of examples well agree with Beal’s Conjecture was questioned by W. Naduna Child Student of our School that gave foundation to our investigation on what is said to be known as Beal’s Conjecture. What we have given is minimally sufficient to prove Beal’s Conjecture. This is an exposition in the field of basic mathematics education rather than rigor and abstractness that leads to unreadability. are interesting number identities observed by Indian Mathematical Genius Ramanujan [1] , [2] .

There are bigger five set of number identities given by Don Zagier but non of them fit with Beal’s Conjecture due to Beal’s restriction all exponents must be greater than 2 then only such must be divisible by a prime number such as

So far none other primes could be found as satisfying Beal’s conjecture other than 2, 3 prime numbers which are the smallest 1 is not prime. It is difficult to expect more than what is said. But Robert Kanigel [2] in page 343 under the paragraph three states in his novel book on Srinivasa Ramanujan [2] “Let denote the sum of the sth powers of divisors of n”, Ramanujan had begun. If n = 6 for example, its divisors are 6, 3, 2 and 1. So that if, say 3, “the sum of the sth powers of the divisors”, is just But how to calculate generally? that question led Ramanujan, after fifteen pages, to the tau function, whose properties, Hardy would write twenty years later, “are very remarkable and still very imperfectly understood”. As in so much of analytical number theory, stepping through the open door of a simple- seeming problem had led into a mathematical labyrinth of formidable complexity.

Now let us get back to our answering based on what is said by Robert Kanigel [2] on some piece of work by Mathematical Genius Ramanujan

the second example that coincided with Beal’s Conjecture that we have already noted. So rest also must be derivable from Ramanujan’s work commented by Robert Kanigel [2] a Great Novelist historian in mathematics of Srinivasa Iyengar Ramanujan and his life. Answer to Beal’s Conjecture must fall from Goddess Namagiri of Namakkal the Ramanujan’s Divine dietyof great faith in the state of Tamilnadu in India the southern part of land of ancient Barat Now consider

satisfying Beal’s Conjecture could be derived from sum of 1th powers of divisors of 2n−1 including 1 and itself, based on the mathematics of Ramanujan’s paper on certain arithmetical functions appeared in the transactions of the Cambridge Philosophical Society, XX11, No. 9, 1916, 159 - 184. If other number identities exist they all might be derivable by the same technique introduced here at last a genuine approach to finalize the story. Further

n = 4,15 is not a prime factor, n = 6,63 is not a prime factor are very simple counter examples to Beal’s Conjecture, So it is very clear factor need not be prime always but can be prime or not prime. Very simple mathematics founded by W. Nadun, Kanigel, S. Ramanujan at last but not least defeated Beal’s Claim of a prime factor always for exponents greater than 2 for Beal-Fermat Equation a generalization of Fermat’s Theorem at Last and Beal’s Theorem at First. Andrew Beal was very sincere if at least few counter examples are found for his famous conjecture now he is provided with two such cases. If you computerize it with a programming language it may give many counter examples as well as examples satisfying Beal. In our discussion, we end this story on Beal’s Conjecture. Wikipedia on Beal can provide more information. We have provided sufficient ground in support of Beal’s Conjecture as well as against it.

2. A Solution to Fermat’s Marginal Conjecture in His Diary Notes

there are no positive integers for recorded by Fermat.

Now assume there are such positive integer with no common factors satisfying Fermat’s Conjecture given for and take

since are positive integers, contradicting the original assumption of no common factors so such positive integers cannot exist for the given equation confirming Fermat’s marginal diary note. First we assumed that, there are positive integers with no common factors for higher n than two for the Fermat’s Equation that we have started with. Later with that assumption we could be able to come to a conclusion mathematically x is a multiple of y and z that contradict our own assumption of no common multiples. Due to the contradiction that we could have obtained we decided our original assumption of existence of positive integers with no common multiples is incorrect for higher n than two. This is famous reduction ad absurdum that is method of reduction to absurdity introduced by Pythagoras a logical deduction methodology. It has sufficient ground for a simple proof as expected by Fermat what he said is that, the proof is very simple but he does not have sufficient space to write it in his marginal diary note. The case of m equal to one provides a clear comprehension of the logic behind. It provides the missing ground of a simple proof as said by Fermat himself unnoticed before and when proofs are too long readers drop it.

3. A Solution to Fermat’s Last Theorem Found in 1982-1983 Period by Galois Theory of Groups

Fermat’s Last Theorem states does not have positive integer solutions for. Take & are positive integers. Then and expand by Newton’s Binomial Theorem and bring all ter- ms to the left hand side keeping right hand side zero. By Abel-Galois Theory it is not solvable by radicals for which are quantic or higher order polynomial equations so no roots can be extracted for this general equation the existence of positive integer solutions cannot be predicted. In general no information can be retrieved in this regard from higher order polynomials whose degree is greater than 4. But for this transformation can be used to tackle the non-existence of integer solutions and for n = 2 this leads to the Pythagorean triplets. It is not difficult to work out the advance details and abstract algebra needed are well available in text books [3] , [4] .

Few technical points can be noted as follows. The resulting polynomial equation is


are the roots

is the elementary symmetric function. is the coefficient of in the polynomial.

be the elementary symmetric functions in the in-determinates then every symmetric function in over F is a rational function of the elementary symmetric functions. Also, is a finite normal extension of of degree and the Galois group of this ex- tension is isomorphic to. Let G be a finite group, with identity element, G is said to be a Solvable group if there exists a Sequence of Subgroups

Such that for is a Normal Subgroup of G with an Abelian Factor Group. For quadratic equation Galois Group consists of the identity and a map interchanging. For cubic equation the Galois group has a series with Abelian quotients.

For quartic equation the Galois group has a series with abelian quotients where.

Therefore are solvable so that corresponding quadratic, cubic, quartic equations are solvable by radicals.

Alternating Group, has no normal subgroups whatever except itself and identity. Therefore Symmetric Group, is not solvable if. Thus, any polynomial whose Galois Group [5] is is not solvable by radicals.

Therefore for no radical solutions for exists so no inte- ger solutions for x are derivable radically for this general form of the equation. It has sufficient base of a proof not noticed before.

As produce Pythagorean triplets we have found

gives rise to them as an example take p = 0 leads to the first Pythagorean triplet. This new formula was discovered by us using the technique introduced here at the beginning.

4. A Marginal Proof for Fermat’s Last Theorem by Calculus

Start with and differentiate it with respect to x.


is the discriminant

for real roots to exists where are assumed to be positive inte-

gers, consider the case with so that

leads to complex number which ends up in a contradiction due to the original assumption of existence of positive integer for Fermat’s equation.

Therefore by the method called Reductio ad Absurdum that is reduction to absurdity Fermat’s Criteria get satisfied that there are no positive integer solutions when for the Fermat’s Conjectural Equation. This is a marginal proof that is a very short exposition that was expected by Fermat in his original diary notes.

so there is a maxima at

this point but does not exist due tonon availability of real positive integers for zero discriminant that must be what Frey has stated as forbidden of existence.

Further for For Frey’s Curve with the starting formula forbidden to exist & it cannot be plotted with Fermat’s conditions under the circumstances arose. Reductio ad Absurdum that is reducing to absurdity the logical deduction methodology was used. Related advance material are well available in the current mathematical literature only missing parts are noted in our exposition to avoid unreadability. It has sufficient ground to simplify the proof.

5. Proof of Riemann Hypothesis

A proof is given for the Riemann Hypothesis in the strictly open interval and further it is proved what exactly happens on the boundary lines at in the closed interval.

ber. What Hypothesis says is that only on line in the open interval

This completes the proof which has sufficient ground unnoticed before for the long awaited Riemann Hypothesis strictly in the open interval conjectured by Bernhard Riemann a German Mathematician who found the Riemann definition of Integral & Riemann Geometry used by Albert Einstein in the formulation of General Theory of Relativity. Further it is worth to mention something more than Riemann that did not appear under his conjecture that he has missed at his time for the benefit of mathematics

& we keep them for readers

to come up with their sketch of proofs following similar line of thought the existence of two more zero lines and beyond this closed range no more such lines exists.
