5. Publications

All printed research publications (items 1-70), preprints (71-155), publications of general interest (156-180), and printed teaching material (181-182) in 1997 due to the personnel (and to a few other persons affiliated to the department) are listed below in alphabetic order in Sections 5.1, 5.2, 5.3, and 5.4, respectively. Of these [36] and [57] are Ph.D. theses, and [2] a monograph. All numbers of the preprint series of the department that appeared in 1997 are listed in Section 5.2. For technical reasons the coverage of the publications does not exactly fit with the calendar year 1997; four of the publications appeared already in 1995 and 17 in 1996; moreover, the real printing year of [69] is not 1997 but will be 1998. Section 5.5 contains a list of all authors belonging to the personnel (or some to the guests), with references to the items authored by these persons.
