我们将一个素数幂导子的虚阿贝尔数域\(K\)的相对类数表示为一种马耶(Maillet)行列式。由此,我们根据\(2d\)次幂剩余的和,得到了导子为\(p\)(\(p>3\)为素数)且次数\(2d = [K:\mathbb{Q}]<10\)的数域\(K\)的显式相对类数公式。特别地,给出了\(p<10000\)的表格。
We express the relative class number of an imaginary abelian num- ber field K of prime power conductor as a sort of Maillet determinant. Thereby we obtain explicit relative class number formulas for fields K of conductor p , p > 3 prime, and degree 2d = (K: Q) < 10, in terms of sums of 2d-power residues. In particular, tables are given for p < 10000.
