At first glance, the Dedekind sums seem to be a highly specialized subject. These sums denoted by*h, k*be integers,

Here and in the following the symbol ((*x*)) is defined by

(2)*x*is not an integer, if*x*is an integer,

with [*x*] the greatest integer not exceeding*x*. This is the well-known sawtooth function of period 1 (see Figure 1),

which at the points of discontinuity takes the mean value between the
