摘要：           We generalize a number of tools and theorems to search for difference families in cyclic groups, to the more general setting of arbitrary finite abelian groups. In particular, these include the power spectral density (PSD) test and the method of compression. Some illustrative examples will be presented, using Maple's GroupTheory package. This is joint work with Dragomir Z. Djokovic (University of Waterloo) pre-publication available at: https://arxiv.org/abs/1801.07627
