文摘In this paper, we define multiple Dedekind sums by products of Bernoulli functions. From the Fourie expansions of Bernoulli functions, we express the Dedekind sums as series representatios. Then by a combinatorial-geometric method, we give a new proof of a Knopp-type identity for the Dedekind sums.
