On some recent progress of the Schinzel hypothesis over polynomial rings
Coordinació
Descripció
In \cite[page 188]{Schinzelhypothesis}, it was formulated the so--called \textit{Schinzel (H) hypothesis}, which can be stated as follows. \begin{con} Let $P_1,\ldots,P_s$ be polynomials in $\mathbb{Z}[x]$, all of degree at least one, satisfying the following condition. \[ \text{There is no prime }p\in\mathbb{Z}\text{ dividing all values }\prod_{i=1}^s P_i (m),\ m\in\mathbb{Z}. \] Then, there are infinitely many integers $m\in\mathbb{Z}$ such that $P_1 (m),\ldots,P_s (m)$ are prime numbers. \end{con} The conjecture is, of course, known in the case $s=1$ when $P_1$ is a polynomial of degree one; this is nothing but the classical Dirichlet's theorem on primes in arithmetic progressions. To the best of our knowledge, the case $s>1$ is completely open. The goal of these lectures is to explain how Bodin, Deb\`es and Najib have recently proved \cite{bodin2020schinzel} the Schinzel hypothesis replacing the ring of integers $\mathbb{Z}$ by a polynomial ring $A[x_1,\ldots,x_m]$, where $A$ is, roughly speaking, a ring where the classical Hilbert's irreducibility theorem holds.
