The series is devoted to the publication of monographs and high-level textbooks in mathematics, mathematical methods and their applications. Apart from covering important areas of current interest, a major aim is to make topics of an interdisciplinary nature accessible to the non-specialist.

The works in this series are addressed to advanced students and researchers in mathematics and theoretical physics. In addition, it can serve as a guide for lectures and seminars on a graduate level.

The series de Gruyter Studies in Mathematics was founded ca. 30 years ago by the late...

_ .... _---------- ------------ Wahrend der letzten zehn Jahre konnte: man eine Neubelebung des Interesses fur die Potentialtheorie beobachten. Zwei Ursachen lassen dies verstandlich erscheinen: Einmal die innere Weiterentwicklung der Potentialtheorie. welche nach der Erfassung moglichst umfangreicher Klassen von Differentialgleichungen und Kernen drangt, zum anderen die Entwicklung der Theorie der Markoffschen Prozesse und der vor allem durch die bahnbrechende Arbeit von G.A.HUNT erwirkte Bruckenschlag hinuber zur Potentialtheorie. Die genannte innere Entwicklung der Potentialtheorie hat,...

Leading research in the active field of virology is given coverage in this volume. Based on contributions from a meeting in Giessen, FRG, organized by the Deutsche Forschungsgemeinschaft, the reviews represent international experience from Japan, Europe and North America. The most interesting topics in current virus research are included, such as: leukemogenesis by retroviruses, coding strategy of arena- and coronaviruses, slow virus infections, virus-induced membrane fusion, antiviral agents, pathogenetic mechanisms of influenza- and retroviruses, and recombinant vaccinia virus.
