摘要

我们证明了先前结果的更强形式,即对于满足通常必要条件的 n 组整数多项式,辛泽尔假说 100%成立,其中多项式所代表的素数受到 Legendre 符号以及上下限的额外约束。我们建立了投影线上一般对角圆锥束的布劳尔群的三性。最后,我们给出了某些自然系中对角圆锥束具有有理点的概率的明确下限。

Generic Diagonal Conic Bundles Revisited
We prove a stronger form of our previous result that Schinzel’s Hypothesis holds for 100% of n-tuples of integer polynomials satisfying the usual necessary conditions, where the primes represented by the polynomials are subject to additional constraints in terms of Legendre symbols, as well as upper and lower bounds. We establish the triviality of the Brauer group of generic diagonal conic bundles over the projective line. Finally, we give an explicit lower bound for the probability that diagonal conic bundles in certain natural families have rational points.
