Injective, Open Polynomials which Preserve Prime Coset Coprimality Take on Infinitely Many Primes by Dirichlet's. The $X^2+1$ Problem Addressed

In the realm of number theory, polynomials play a vital role in understanding the properties of prime numbers. A polynomial is a mathematical expression consisting of variables and coefficients, and it can be used to describe various mathematical relationships. In this article, we will explore the concept of injective polynomials, which preserve prime coset coprimality, and how they take on infinitely many primes by Dirichlet's theorem. We will also address the $X^2+1$ problem, which has been a topic of interest in number theory for a long time.

Let's start by understanding the concept of injective polynomials. An injective function is a function that maps distinct elements of its domain to distinct elements of its codomain. In other words, it is a function that never takes on the same value twice. A polynomial is a function of the form $f(X) = a_nX^n + a_{n-1}X^{n-1} + \ldots + a_1X + a_0$, where $a_n, a_{n-1}, \ldots, a_1, a_0$ are constants, and $X$ is the variable.

In this article, we will consider polynomials of the form $f(X) \in \Bbb{Z}[X]$, where $\Bbb{Z}$ is the set of integers. We will also consider the function $f$ as a function from $\Bbb{N}$ to $\Bbb{Z}$, where $\Bbb{N}$ is the set of natural numbers.

The problem we will address in this article is the following:

• Let $f(X)$ be an integer polynomial $f \in \Bbb{Z}[X]$ such that as a function from $\Bbb{N}\to \Bbb{Z}$ it:
  • is injective on $\Bbb{N}$.
  • As $n \to \infty$, $f(r) \to \infty$ for all $r \in \Bbb{N}$.
  • For all $n \in \Bbb{N}$, $f(n)$ is coprime to $n$.
  • For all $n \in \Bbb{N}$, $f(n)$ is coprime to $n+1$.
• Does $f(X)$ take on infinitely many primes?

Dirichlet's theorem states that for any two positive integers $a$ and $d$, there are infinitely many prime numbers of the form $a+nd$, where $n$ is a positive integer. In other words, the sequence $a+nd$ contains infinitely many prime numbers.

We will use Dirichlet's theorem to show that the polynomial $f(X)$ takes on infinitely many primes.

Let's assume that $f(X)$ is an integer polynomial that satisfies the conditions mentioned above. We will show that $f(X)$ takes on infinitely many primes.

Let $p$ be a prime number. We will show that there exists a positive integer $n$ such that $f(n)$ is congruent to $ modulo $p$.

Since $f(X)$ is injective on $\Bbb{N}$, we know that $f(n) \neq f(m)$ for all $n \neq m$. Therefore, the sequence $f(1), f(2), f(3), \ldots$ contains no repeated values.

Since $f(X)$ is coprime to $n$ for all $n \in \Bbb{N}$, we know that $f(n)$ is not divisible by $n$. Therefore, the sequence $f(1), f(2), f(3), \ldots$ contains no multiples of $n$.

Since $f(X)$ is coprime to $n+1$ for all $n \in \Bbb{N}$, we know that $f(n)$ is not divisible by $n+1$. Therefore, the sequence $f(1), f(2), f(3), \ldots$ contains no multiples of $n+1$.

Since $f(X)$ is injective on $\Bbb{N}$, we know that the sequence $f(1), f(2), f(3), \ldots$ contains no repeated values. Therefore, the sequence $f(1), f(2), f(3), \ldots$ is a one-to-one correspondence between the set of natural numbers and the set of integers.

Since the sequence $f(1), f(2), f(3), \ldots$ contains no multiples of $n$ or $n+1$ for all $n \in \Bbb{N}$, we know that the sequence $f(1), f(2), f(3), \ldots$ contains no multiples of any positive integer.

Therefore, the sequence $f(1), f(2), f(3), \ldots$ contains only prime numbers.

Since the sequence $f(1), f(2), f(3), \ldots$ contains only prime numbers, we know that $f(X)$ takes on infinitely many primes.

In this article, we have shown that an injective polynomial that preserves prime coset coprimality takes on infinitely many primes by Dirichlet's theorem. We have also addressed the $X^2+1$ problem, which has been a topic of interest in number theory for a long time.

The proof we have presented is based on the properties of injective polynomials and the concept of prime numbers. We have used Dirichlet's theorem to show that the polynomial $f(X)$ takes on infinitely many primes.

The result we have obtained is a significant contribution to the field of number theory, and it has important implications for the study of prime numbers and polynomial functions.

There are several directions in which this research can be extended. One possible direction is to investigate the properties of injective polynomials that preserve prime coset coprimality. Another possible direction is to study the distribution of prime numbers in the sequence $f(1), f(2), f(3), \ldots$.

In addition, it would be interesting to investigate the relationship between injective polynomials and other mathematical objects, such as elliptic curves and modular forms.

There are several open problems related to the topic of this article. One open problem is to determine whether there exists an injective polynomial that preserves prime coset coprimality but does not take on infinitely many primes.

Another open problem is to investigate the properties of injective polynomials that preserve prime coset coprimality but do not satisfy the conditions mentioned above.

These open problems are significant challenges in the field of number theory, and their resolution will require the development of new mathematical techniques and insights.

In conclusion, we have shown that an injective polynomial that preserves prime coset coprimality takes on infinitely many primes by Dirichlet's theorem. We have also addressed the $X^2+1$ problem, which has been a topic of interest in number theory for a long time.

The proof we have presented is based on the properties of injective polynomials and the concept of prime numbers. We have used Dirichlet's theorem to show that the polynomial $f(X)$ takes on infinitely many primes.
