论文摘要
在本文中,我们研究了一些实际循环四分之一数字字段的班级组的2级。确切地说,我们考虑了二次子字段是q(\ sqrt {l}),其中l符合5 modulo 8是素数。
In this paper, we investigate the 2-rank of the class group of some real cyclic quartic number fields. Precisely, we consider the case where the quadratic subfield is Q(\sqrt{l}) with l congruent to 5 modulo 8 is a prime.
