关于$\mathrm{GU}(3,1)$上非平凡模形式和Eisenstein同余的Iwasawa-Greenberg猜想

Iwasawa-Greenberg main conjecture for non-ordinary modular forms and Eisenstein congruences on $\mathrm{GU}(3,1)$

Francesc Castella, Zheng Liu, Xin Wan

摘要:

本文利用Klingen Eisenstein级数与$\mathrm{GU}(3,1)$上的尖点形式之间的同余关系,证明了Iwasawa-Greenberg主猜想关于权为2的尖点形式与高权的普通CM形式的Rankin-Selberg积的单侧整除性,推广了作者的早期结果,允许非普通的尖点形式.主要结果是一个关键的输入在第三作者的证明小林的$\pm$ -主要猜想超奇椭圆曲线。这里的新内容是沿着一个适当的较小的权空间发展一个半普通的Hida理论,并研究半普通的Eisenstein族。

英文摘要:

In this paper we prove one side divisibility of the Iwasawa-Greenberg main conjecture for Rankin-Selberg product of a weight two cusp form and an ordinary CM form of higher weight, using congruences between Klingen Eisenstein series and cusp forms on $\mathrm{GU}(3,1)$, generalizing earlier result of the third-named author to allow non-ordinary cusp forms. The main result is a key input in the third author's proof for Kobayashi's $\pm$-main conjecture for supersingular elliptic curves. The new ingredient here is developing a semi-ordinary Hida theory along an appropriate smaller weight space, and a study of the semi-ordinary Eisenstein family.
