## Theorem

There is no algorithm to determine whether a given polynomial Diophantine equation with integer coefficients has an integer solution.

## Proof

## Historical Note

**Hilbert's $10$th problem** was the question:

*Given a Diophantine equation with any number of unknown quantities and with rational integer numerical coefficients: To devise a process according to which it can be determined in a finite number of operations whether the equation is solvable in rational integers.*

The MRDP Theorem has shown that recursively enumerable sets are equivalent to Diophantine sets.

Matiyasevich's Theorem shows that solutions to Diophantine equations may grow exponentially.

Yuri Vladimirovich Matiyasevich proved this in $1970$ by using a method involving Fibonacci numbers, which grow exponentially.

## Hilbert $23$

This problem is no. $10$ in the Hilbert $23$.
