    Description / Table of Contents: We have long moved on from a mere information age to the era of big data. Here, databases represent both the enormous potential for gaining knowledge of data collection and the alarming information excesses of digital culture. Furthermore, the term refers to concrete technologies and processes of gathering and accessing digital information. Media theory has to locate databases in between these very different conceptions. Marcus Burkhardt retraces the history of databases and asks how technical procedures of processing digital information determine what can be found how in databases and what knowledge can be gained through them. | Wir leben längst nicht mehr nur im Informationszeitalter, sondern in der Ära von Big Data. In dieser steht die Datenbank gleichzeitig für die riesigen Erkenntnispotenziale von Informationssammlungen wie für die bedrohlichen Informationsexzesse der digitalen Medienkultur. Zudem bezeichnet der Begriff konkrete Technologien und Verfahren der Sammlung und Bereitstellung von digitalen Informationen. Zwischen diesen sehr unterschiedlichen Auffassungen gilt es, Datenbanken medientheoretisch zu verorten. Marcus Burkhardt zeichnet die Geschichte der Datenbanken nach und fragt, wie technische Verfahren der Verwaltung digitaler Informationen bedingen, was auf welche Weise in Datenbanken gefunden und durch sie gewusst werden kann.

    Description / Table of Contents: This is the long awaited follow-up to Lie Algebras, Part I which covered a major part of the theory of Kac-Moody algebras, stressing primarily their mathematical structure. Part II deals mainly with the representations and applications of Lie Algebras and contains many cross references to Part I. The theoretical part largely deals with the representation theory of Lie algebras with a triangular decomposition, of which Kac-Moody algebras and the Virasoro algebra are prime examples. After setting up the general framework of highest weight representations, the book continues to treat topics as the Casimir operator and the Weyl-Kac character formula, which are specific for Kac-Moody algebras. The applications have a wide range. First, the book contains an exposition on the role of finite-dimensional semisimple Lie algebras and their representations in the standard and grand unified models of elementary particle physics. A second application is in the realm of soliton equations and their infinite-dimensional symmetry groups and algebras. The book concludes with a chapter on conformal field theory and the importance of the Virasoro and Kac-Moody algebras therein.

    Description / Table of Contents: The study of non-linear dynamical systems nowadays is an intricate mixture of analysis, geometry, algebra and measure theory and this book takes all aspects into account.Presenting the contents of its author' graduate courses in non-linear dynamical systems, this volume aims at researchers who wish to be acquainted with the more theoretical and fundamental subjects in non-linear dynamics and is designed to link the popular literature with research papers and monographs.All of the subjects covered in this book are extensively dealt with and presented in a pedagogic form. These include the presentation of an environment for the route to chaos by quasi-periodicity (which is related to the Landau-Lifschitz and Ruelle-Takens scenario's concerning the onset of turbulence); the theories of 1-dimensional dynamics, singularities in planar vector fields, and quasi-periodicity in dissipative systems.
