AI总结:

摘要:

我们研究素数变量中多项式方程的密度和划分性质。考虑形如$a_1h(x_1)+\cdots+a_sh(x_s)=b$的方程,其中$a_i$和$b$是固定系数,$h$是任意$d$次整系数多项式。当变量数至少为$(1+o(1))d^2$时,我们建立了该方程对素数的任意有限染色存在单色非平凡解的充要条件。类似地,我们刻画了这类方程在任意正相对上密度素数集上存在解的情况。在这两种情况下,我们得到了计数结果,为素数中单色或稠密解的数量提供了渐近紧的下界。我们的主要新要素是素数多项式玻尔集基数的一致下界。

英文摘要:

We study density and partition properties of polynomial equations in prime variables. We consider equations of the form $a_1h(x_1) + \cdots + a_sh(x_s)=b$, where the $a_i$ and $b$ are fixed coefficients, and $h$ is an arbitrary integer polynomial of degree $d$. Provided there are at least $(1+o(1))d^2$ variables, we establish necessary and sufficient criteria for this equation to have a monochromatic non-constant solution with respect to any finite colouring of the prime numbers. We similarly characterise when such equations admit solutions over any set of primes with positive relative upper density. In both cases, we obtain counting results which provide asymptotically sharp lower bounds for the number of monochromatic or dense solutions in primes. Our main new ingredient is a uniform lower bound on the cardinality of a prime polynomial Bohr set.
