Title in Portuguese
A conjectura de Bateman-Horn e o Lambda-cálculo de Golomb
Keywords in Portuguese
Conjectura de Bateman-Horn
Lambda-cálculo de Golomb
teoremas abelianos
Abstract in Portuguese
A Conjectura de Bateman-Horn dá condições sobre uma família de polinômios com coeficientes inteiros $f_1(X),\dots,f_k(X)$ para que hajam infinitos $n \in \N$ tais que $f_1(n),\dots,f_k(n)$ sejam todos primos, e determina qual deve ser o comportamento assintótico de tais inteiros $n$. Neste texto, vamos estudar essa conjectura, assim como um método desenvolvido por Solomon W. Golomb que pode ser usado para demonstrá-la. Veremos que esse cálculo prova a Conjectura de Bateman-Horn a menos da troca de um limite com uma série infinita, que é o único passo ainda não provado desse método. Também estudaremos uma tentativa para solucionar esse problema por meio do uso de teoremas abelianos de regularidade, e provaremos que teoremas tão gerais não são suficientes para provar a troca do limite com a série.
Title in English
The Bateman-Horn conjecture and Golomb's Lambda-method
Keywords in English
Abelian theorems
Bateman-Horn conjecture
Golomb's Lambda-method
Abstract in English
Given a family of polynomials with integer coefficients $f_1(X),\dots,f_k(X)$, one would like to answer the following question: does there exist infinitely many $n \in \N$ such that $f_1(n),\dots,f_k(n)$ are all primes? Schinzel conjectured that if these polynomials satisfy certain simple conditions, then the answer to this question is affirmative. Assuming these conditions, Bateman and Horn proposed a formula for the asymptotic density of the integers $n \in \N$ such that $f_1(n),\dots,f_k(n)$ are all primes. In this text, we shall study the Bateman-Horn Conjecture, as well as a method proposed by Solomon W. Golomb that may be used to prove this conjecture. We shall see that Golomb's $\Lambda$-method would prove the Bateman-Horn Conjecture, except for a single unproved step, namely, the commutation of a limit with an infinite series.
