The theme of this book is the self-generation of information by the self-modification of systems. The author explains why biological and cognitive processes exhibit identity changes in the mathematical and logical sense. This concept is the basis of a new organizational principle which utilizes shifts of the internal semantic relations in systems. There are mathematical discussions of various classes of systems (Turing machines, input-output systems, synergetic systems, non-linear dynamics etc), which are contrasted with the author's new principle. The most important implications of this include a new conception on the nature of information and which also provides a new and coherent conceptual view of a wide class of natural systems. This book merits the attention of all philosophers and scientists concerned with the way we create reality in our mathematical representations of the world and the connection those representations have with the way things really are.

The term "sustainability" has entered the lexicon of many academic disciplines and fields of professional practice, but to date does not appear to have been seriously consid ered within the systems community unless, perhaps, under other guises. Within the wider community there is no consensus around what sustainability means with some authors identifying 70 to 100 definitions of the term. Some see sustainability as the precise and quantifiable outcomes of biological systems whilst others see it in terms of processes rele vant to personal and organizational change with the potential to effect changes in our rela tionships with out environments. Internationally it has been increasingly used in relation to the term "sustainable development"--a term popularised by the Brundland Commis of definitions sion's report in 1987 entitled "Our Common Future. " Despite this diversity and polarised perception on its utility, unlike many other popular terms, it has not had its time and subsided quietly from our language. It is therefore timely for the systems com munity to explore the relationship between systems and sustainability in a range of con texts. Participants in this, the 5th International Conference of the United Kingdom Systems Society (UKSS), have been invited to reflect critically on the contribution of sys tems thinking and action to sustainability-to the sustainability of personal relationships, the organizations in which live and work, and our "natural" environment.

Dieses Buch ist eine Einführung in die Differentialgeometrie. Zunächst geht es um die klassischen Aspekte wie die Geometrie von Kurven und Flächen, bevor dann höherdimensionale Flächen sowie abstrakte Mannigfaltigkeiten betrachtet werden. Die Nahtstelle ist dabei das zentrale Kapitel "Die innere Geometrie von Flächen". Dieses führt den Leser bis hin zu dem berühmten Satz von Gauß-Bonnet, der ein entscheidendes Bindeglied zwischen lokaler und globaler Geometrie darstellt. Die zweite Hälfte des Buches ist der Riemannschen Geometrie gewidmet. Den Abschluss bildet ein Kapitel über "Einstein-Räume", die eine große Bedeutung sowohl in der "Reinen Mathematik" als auch in der Allgemeinen Relativitätstheorie von A. Einstein haben. Es wird großer Wert auf Anschaulichkeit gelegt, was durch zahlreiche Abbildungen unterstützt wird. Im Laufe der Neuauflagen wurde der Text erweitert, neue Aufgaben wurden hinzugefügt und am Ende des Buches wurden zusätzliche Hinweise zur Lösung der Übungsaufgaben ergänzt. Der Text wurde für die fünfte Auflage gründlich durchgesehen und an einigen Stellen verbessert.
