Abstract

We propose a fast method of calculating the p-part of the class numbers in certain non-cyclotomic Zp-extensions of an imaginary quadratic field using elliptic units constructed by Siegel functions. We carried out practical calculations for p = 3 and determined λ-invariants of such Z3-extensions which were not known in our previous paper.

类数计算使用西格尔函数

本文提出了一种利用西格尔函数构造的椭圆单位快速计算虚二次域非分环zp扩展中类数p部分的方法。我们对p = 3进行了实际计算，并确定了这类z3扩展的λ-不变量，这是我们在以前的文章中所不知道的。
