Set-valued analysis is an important component of the stuy of differential inclusions, which in turn provide an efficient tool for the modelling and analysis of dynamic phenomena which evolve from external actions, either under control or in a state of uncertainty. Intensive research in this field has been carried out during the past decade, and significant results have been obtained in both the qualitative theory and the contructive methods. Topics like optimal control, viability, the deterministic treatment of the issues of sustainablitiy, adaptive control, and stabilization of uncertain systems are among the main motivations for this development. The Systems and Decision Sciences Program (SDS) of the International Institute for Applied Systems Analysis (ILASA) has vigorously promoted this development, with major emphasis on the methods for modelling, constructive analysis, and decision-making under uncertainty. The papers in this volume represent a selection of expanded and updated talks which were first presented at an SDS sponsered International Workshop in Pamporovo, Bulgaria, in September 1990. The editors offer this selection as a distillation of some of the most important work in the field, spanning many countries and schools of thought, and bringing the subject up to date.
The book will be extremely valuable to research workers in mathematical control theory, as well as in such fields as economics, biology, and systems science
