AI总结:

本文为支持Greenberg关于椭圆曲线$p$-准素Selmer群$μ$-不变量的猜想,利用Bhargava和Shankar的5-Selmer群分布结果,证明了正密度的在5处好常约化的椭圆曲线的5-准素岩泽$μ$、$λ$-不变量同时为零。

摘要:

给定素数$p\geq 5$,Greenberg猜想预测,对于大多数在$p$处具有好常约化的椭圆曲线,其$p$-准素Selmer群的$μ$-不变量应为零。为支持该猜想,本文证明了存在明确正密度的有理数域$\mathbb{Q}$上的椭圆曲线$E_{/\mathbb{Q}}$,其5-准素岩泽$μ$-不变量与$λ$-不变量同时为零。所研究的椭圆曲线在5处具有好常约化,按高度排序。该结果是利用Bhargava和Shankar关于$\mathbb{Q}$上椭圆曲线5-Selmer群分布的工作证明的。

英文摘要:

Given a prime $p\geq 5$, a conjecture of Greenberg predicts that the $μ$-invariant of the $p$-primary Selmer group should vanish for most elliptic curves with good ordinary reduction at $p$. In support of this conjecture, I show that the $5$-primary Iwasawa $μ$- and $λ$-invariants simultaneously vanish for an explicit positive density of elliptic curves $E_{/\mathbb{Q}}$. The elliptic curves in question have good ordinary reduction at $5$, and are ordered by their height. The results are proven by leveraging work of Bhargava and Shankar on the distribution of $5$-Selmer groups of elliptic curves defined over $\mathbb{Q}$.
