含平方元的D(n)-五元组

D(n)-quintuples with square elements

Andrej Dujella, Matija Kazalicki, Vinko Petričević

摘要:

对于整数n,m个不同的非零整数{a_1,a_2,.,a_m},使得a_i a_j+n是完满平方,对所有0<i<j<m+1,称为D(n)-m-元组。本文证明了存在无穷多个本质不同的具有平方元的D(n)-五元组。我们通过在A^2的某个双覆盖上构造亏格为1的曲线,得到了这个结果。

英文摘要:

For an integer n, a set of m distinct nonzero integers {a_1,a_2,...,a_m} such that a_i a_j+n is a perfect square for all 0<i<j<m+1, is called a D(n)-m-tuple. In this paper, we show that there are infinitely many essentially different D(n)-quintuples with square elements. We obtained this result by constructing genus one curves on a certain double cover of A^2 branched along four curves.
