By using Fourier transforms and based on group representations and character theory, the eigenvalues of the Cayley graph on the direct product group of bicyclic groups and cyclic groups are explicitly given, and a closed-form formula for the Kirchhoff index of the graph is established. Meanwhile, two examples are presented to illustrate the applicability of our obtained theoretical results.
