双正则丢番图四元组

Doubly regular Diophantine quadruples

Andrej Dujella, Vinko Petričević

摘要:

对于非零整数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1 <= i < j <= m,称为D(n)-m-元组。本文利用正则丢番图m-元组和某些椭圆曲线族的性质,证明了存在无穷多个由完满平方构成的本质不同的集合,它们同时是具有不同非零平方n_1和n_2的D(n_1)-四元组和D(n_2)-四元组.

英文摘要:

For a nonzero 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 1 <= i < j <= m, is called a D(n)-m-tuple. In this paper, by using properties of so-called regular Diophantine m-tuples and certain family of elliptic curves, we show that there are infinitely many essentially different sets consisting of perfect squares which are simultaneously D(n_1)-quadruples and D(n_2)-quadruples with distinct non-zero squares n_1 and n_2.
