AI 中文摘要

在这项工作中,我们建立了一个判定准则,用于分类在正整数集中无解的椭圆曲线。特别地,我们证明:若 $E: y^2 = Ax^3 + Bx^2 + Cx + D$ 是一条椭圆曲线,其中 $A$、$B$、$C$ 和 $D$ 是曲线的系数,$p$ 是一个满足 $p \equiv 1 \pmod{4}$ 的素数,且 $(x,y)$ 是正整数点,则当 $$ -3A + C \equiv -1 \pmod{4}, $$ $$ A - B + C \equiv -1 \pmod{4}, $$ 且 $$ p^2 = A - B + C - B, $$ 时,曲线 $E$ 不存在正整数解,即 $E(\mathbb{Z}^{+}) = \varnothing$。此外,我们通过引入线性代数技术来推广这一准则。具体而言,我们引入了一种矩阵构造,以证明一族椭圆曲线不存在正整数解。

英文摘要

In this work, we establish a criterion for classifying elliptic curves that have no solutions in the set of positive integers. In particular, we prove that if $E: y^2 = Ax^3 + Bx^2 + Cx + D$ is an elliptic curve where $A$, $B$, $C$, and $D$ are coefficients of the curve, and $p$ is a prime number where $p \equiv 1 \pmod{4}$, and $(x,y)$ is a positive integer point, then if $$ -3A + C \equiv -1 \pmod{4}, $$ $$ A - B + C \equiv -1 \pmod{4}, $$ and $$ p^2 = A - B + C - B, $$ then there are no positive solutions for the curve $E$, where $E(\mathbb{Z}^{+}) = \varnothing$. Furthermore, we generalize this criterion by incorporating techniques from linear algebra. Specifically, we introduce a matrix construction to establish the nonexistence of positive integer solutions for a family of elliptic curves.
