关于Dedekind和的等式

On the equality of Dedekind sums

Kurt Girstmair

摘要:

证明了判定两个Dedekind和$S(c,b)$、$S(d,b)$是否相等等价于判定由$b, c, d$定义的Dedekind和是否取某个值。利用这个结果,我们构造了两两相等的Dedekind和的无穷序列。此外,我们证明了一个结果,说有多少Dedekind和$S(d,b)$,$1\le d\le b-1$,可以等于一个给定的$S(c,b)$,如果$b$是一个无平方数。

英文摘要:

We show that deciding the equality of two Dedekind sums $S(c,b)$, $S(d,b)$ is equivalent to deciding whether a Dedekind sum defined by $b, c, d$ takes a certain value. By means of this result we construct infinite sequences of pairwise equal Dedekind sums. Moreover, we prove a result that says how many Dedekind sums $S(d,b)$, $1\le d\le b-1$, may be equal to a given $S(c,b)$ if $b$ is a square-free number.
