14062 Hans-Georg Bartel: Mathematische Medthoden in der Chemie. Spektrum 1996, 390p. DM 88. Abstract methods for chemistry, very carefully explained: Introduction about mathematics and chemistry, sets, mappings and relations (equivalences and partial orders), graph theory (with tournament theory), finite groups with an introduction to representations, concepts of quantum theory and probability, and, in two final chapters, formal concept analysis (60 pages) and cluster analysis (46 pages, with some remarks on ultrametrics).
