Abstract

In this paper, we give the structure of the Iwasawa module \(X=X(k_{\infty })\) of the \(\mathbb {Z}_{2}\)-extension of infinitely many real biquadratic fields k. Denote by \(\lambda , \mu \) and \(\nu \) the Iwasawa invariants of the cyclotomic \(\mathbb {Z}_{2}\)-extension of k. Then \(\lambda =\mu =0 \) and \(\nu =2\).

关于格林伯格对某些实双曲域的猜想
在本文中,我们给出了无穷多个实双四元数域 k 的 \(\mathbb {Z}_{2}\) 扩展的岩泽模块 \(X=X(k_{\infty })\) 的结构。用\(\lambda , \mu \)和\(\nu \)表示k的环(\mathbb {Z}_{2}})-外延的岩泽不变式,那么\(\lambda =\mu =0 \)和\(\nu =2\).
