Prof. Ilias S. Kotsireas, gave a lecture titled "Algorithms for difference families in finite abelian groups" at AMSS on 21, Febrary 2019.
In this talk, they generalized 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 included the power spectral density (PSD) test and the method of compression. Some illustrative examples would be presented, using Maple's Group Theory package. This was joint work with Dragomir Z.Djokovic (University of Waterloo) pre-publication available at: https://arxiv.org/abs/1801.07627
