## Abstract

In this paper, we discuss the symmetry of N-domain and we find that using the symmetry characters of Natural Numbers we can give proofs of the Prime Conjectures: a concise proof of Fermat last theorem Polignac’s conjecture (twins Prime Conjecture) Goldbach Conjecture and Reimann Hypothesis.

### Keywords

N domain; Prime conjectures

### Introduction

We have

N ~（ 0,1,2,3,4,...........） all the natural numbers

n ~（ 1,2,3,4,...........） all the natural numbers excepted 0

P ~（ 2,3,5,7,...........） all the prime numbers

p ~（ 3,5,7,...........） all the odd prime numbers

We notice that

N ~（ 0, n）

P ~（ 2, p)

**1: The proof of twin primes conjecture and goldbach conjecture**

We can define a N, n, P, p, 2n coordinate system shown in **Figures 1** and **2**.

p1, p0, p2 ∈ p

we can get

p1 → n - 1

p0 → n

p2 → n + 1

And

- p1 → - (n-1)

- p0 → -n

- p2 → - (n+1)

So we have

p2 + (- p1) → n + 1 - (-(n-1)) = 2n

This is the proof of Polignac’s conjecture.

And

p2 - p1 → (n+1) - (n-1) = 2

This is the proof of twin primes conjecture.

And

2n = n + 1 + n - 1 → p2 + p1

And

n -1 > 2 n > 3 so 2n > 6

This mean that every even number bigger than six can be divided into two odd prime numbers in N domain.

This is the proof of Goldbach conjecture.

**2: The proof of Riemann Hypothesis**

Riemann Zeta-Function is

Riemann hypothesis

All the Non-trivial zero-point of Zeta-Function Re(s ) = 1/2 .

We have

0 = 1 / 2 - 1 / 2

1 = 1 / 2 + 1 / 2

i2 = - 1

1 / 2 = 1 / 2 * (1/2+1/2i) (1/2-1/2i)

The tr(A)=1/2*n

This is mean that all the non-trivial Zero points of Riemann zetafunction
are on the 1/2 axis just show as Fig.3. This is the proof of
Hilbert–Pólya conjecture. So we give a proof of Riemann Hypothesis
(**Figures 2** and **3**).

**3: A concise proof of fermat’ last theorem**

We can definite a function as

So x + y = n

And x + y ∈ p

x^{2} + y^{2} = n^{2}

But we notice that:

When x + y = 3∈p xy = 3 (x = 1, y + 3)

This is equal to
X^{3} + Y^{3} = n^{3} has no integer solution. This is a
concise proof of Fermat’ last Theorem.
