About 380 years ago, Pierre de Fermat wrote the following idea to
Diophantus's "Arithmetica".
Cubum autem in duos cubos, aut quadratoquadratum in duos quadra-
toquadratos, et generaliter nullam in infnitum ultra quadratum potes-
tatem in duos eiusdem nominis fas est dividere cuius rei demonstrationem
mirabilem sane detexi. Hanc marginis exiguitas non caperet.
Later, this proposition(Fermat's Last Theorem) has continued to be a
presence, such as the One Ring that appeared in JRRTolkien's "Lord
of the Rings". Finally in 1994, it has been proven by Sir Andrew Wiles.
However, interesting Fermat's proof is still unknown. Perhaps this is as-
sumed to algebra category.

Symmetry proves to be a useful concept when it comes to studying some conjectures in Number
theory. This study (english translation of the paper 1304-0060) concentrates on three already well-known conjectures and the
following one:
For any given prime number p, there exists at least one prime number in each and every interval
[kp,(k+1)p[, where k is a non-zero integer that is less than or equal to p.

We prove that the sum of natural numbers is -1/12 of the value of the zeta function by the new
method.

Abel calculated the sum of the divergent series by the Abel summation method. However, we
cannot calculate the sum of natural numbers by the method. In this paper, we calculate the sum of
the natural numbers by the extended Abel summation method.

There are known few interesting properties which distinquish twin primes from the general set of primes, like for instance that 46% of primes smaller than 19000 are Ramanujan primes while about 78% of the lesser of twin primes smaller than 19000 are Ramanujan primes. But seems that a much more trivial observation about the lesser of twin primes escaped attention: from the first 500 numbers which are lesser in a pair of twin primes, 66 of them have the following remarkable property: the sum of their digits is equal to 14.

In this paper, inspired by one of my previous papers posted on Vixra, I make, considering the sum of the digits of an odd integer, a conjecture about an infinity of sets of integers, each one having an infinite number of primes and I also make, considering the sum of the digits of a prime number, two other conjectures.

Using the same method that we used in the paper http://vixra.org/abs/1309.0154 to prove Fermat's Last Theorem in a simpler and truly marvellous way, we demonstrate that Beal's Conjecture yields -- in the simplest imaginable manner; to our effort to proving it.

When defining O(N) as the sum of all divisors of N including himself, it is to be proved that there is no odd number which satisfy the equation:
O(N)=2N
