Some reciprocity formulas for generalized Dedekind-Rademacher sums

In this paper, we study the generalized Dedekind-Rademacher sums considered by Hall, Wilson and Zagier. We establish a formula for the products of two Bernoulli functions. The proof relies on Parseval’s formula, Hurwitz’s formula, and Lerch’s functional equation. The result leads to reciprocity formulas for some generalizations of the classical Dedekind sums. In particular, it is shown that Carlitz’s, Berndt’s, Hall and Wilson’s reciprocity theorems are deduced as special cases.
