论文摘要
在本文中,我们确定了某些类别的实际循环四分之一数字字段的类别组的2级。确切地说,我们考虑了二次子字段是Q(\ sqrt {l})的情况,其中l = 2或prime与1 mod 8。
In this paper, we determine the 2-rank of the class group of certain classes of real cyclic quartic number fields. Precisely, we consider the case in which the quadratic subfield is Q(\sqrt{l}) with l=2 or a prime congruent to 1 mod 8.
