Explicit description of Hopf surfaces and their automorphism groups
The paper deals with the automorphism groups of secondary Hopf surfaces, i.e., Hopf surfaces whose fundamental groups are not cyclic. By using the results of \textit{M. Kato} [J. Math. Soc. Japan 27, 222-238 (1975; Zbl 0301.32025)] the authors give an explicit description of the covering transformations of secondary Hopf surfaces.
