We study the splitting fields of the family of polynomials fn(X)=XnX1. This family of polynomials has been much studied in the literature and has some remarkable properties. In Serre (2003), Serre related the function on primes Np(fn), for a fixed n4 and p a varying prime, which counts the number of roots of fn(X) in Fp to coefficients of modular forms. We study the case n=5, and relate Np(f5) to mod 5 modular forms over Q, and to characteristic 0, parallel weight 1 Hilbert modular forms over Q(19151).

Xn−X−1 的分裂域(特别是 n=5)、素数分解和模形式

我们研究多项式族的分裂域FnX=Xn-X-1。这一系列多项式在文献中得到了大量研究,并且具有一些显着的性质。在 Serre (2003) 中,Serre 将素数函数联系起来pFn,对于固定的n4p一个变化的素数,它计算的根数FnXFp到模形式的系数。我们研究案例n=5,并关联pF5模 5 模块化形式,并且对于特征 0,平行权重 1 希尔伯特模形式19 号151
