虚二次域的类数公式

The class number formula for imaginary quadratic fields

Joseph Lewittes

摘要:

它表明,类数的负判别$D$可以表示在减少分数$\frac{x}{|D|}$,其中$B$是一个整数素数到$D$的基础$B$的扩展。然后将该结果公式化以获得关于$χ(x)$的值的分布的信息,其中$χ$是与$D$相关联的二次字符。这导致在某些情况下的类数的简化公式。

英文摘要:

It is shown that the class number for negative discriminant $D$ can be expressed in terms of the base $B$ expansions of reduced fractions $\frac{x}{|D|}$, where $B$ is an integer prime to $D$. This result is then formulated to obtain information about the distribution of the values of $χ(x)$, where $χ$ is the quadratic character associated to $D$. This leads to simplified formulas for the class number in certain cases.
