摘 要: | 设a,b是非零整数,p1,…,pr是不同的素数,P={±|m1,…,mr是非负整数}.设K是n(n≥3)次代数数域,α1,…,αm∈k(1<m<n),△(α1,…,αm)是α1,…,αm的判别式,f(x1,…,xm)=αNk/Q(α1x1+…+αmxm)∈z[x1,…,xm].本文证明了:当f(x1,…,xm)非退化且Pi△(α1,…,αm)(i=1,…,r)时,方程f(x1,…,xm)=by,x1,…,xm∈z,gcd(x1,…,xm)=1,y∈P至多有(4Sd2)(Sd)组解(x1,…,xm,y),其中d=n!,S=r+ω是b的不同素因数的个数,hA是K的类数.

Abstract: | Let a, b be non-zero integers. Let p1,…,pr be distinct primes, and let P= {± |m1,…, mr are nonnegative integers}. Further let K be an algebraic number fieldof degree n with n ≥3, and let hk denote the class number of K. For α1,…, αm∈K with1 < m < n, let △(α1,… ,αm) denote the discriminant of α1,…,αm, and f(x1,… , xm) =μNK/Q(α1x1 +… + αmxm) ∈ Zx1,…, xm]. In this paper we protve that if f(x1,…, xm) is non-degenerate and pi + △(α1,…,αm) for i=1,…, r, then the equation f(x1,…, xm) = by has at most (4sd2)2 (sd)6 (sd)6 integer solutions (x1,…,xm) satisfy gcd(x1,…,xm) = 1 andy∈P, where d= n!, s = r + ω(b) and ω(b) is the number of distinct prime factors of b. |
