Every formally dual set can be obtained from a primitive formally dual set or, more generally from an irreducible formally dual set.Using several methods, including even set theory and the field-descent method, it is possible to obtain examples of primitive/irreducible formally dual sets as well as non-existence results. A graph search algorithm can be used for further investigation. Overall, primitive formally dual sets seem rare in cyclic groups, but occasionally exist in finite abelian groups. %L 510 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00002581 %U http://purl.uni-rostock.de/rosdok/id00002581 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-rosdok_id00002581-2 %U https://d-nb.info/1293658405/34 %U https://doi.org/10.18453/rosdok_id00002581
