This book concerns the use of concepts from statistical physics in the description of financial systems. The authors illustrate the scaling concepts used in probability theory, critical phenomena, and fully developed turbulent fluids. These concepts are then applied to financial time series. The authors also present a stochastic model that displays several of the statistical properties observed in empirical data. Statistical physics concepts such as stochastic dynamics, short- and long-range correlations, self-similarity and scaling permit an understanding of the global behaviour of economic systems without first having to work out a detailed microscopic description of the system. Physicists will find the application of statistical physics concepts to economic systems interesting. Economists and workers in the financial world will find useful the presentation of empirical analysis methods and well-formulated theoretical tools that might help describe systems composed of a huge number of interacting subsystems.
Nature is not only stable and static but also unstable and dynamical ‑ this has been shown by physics during the last 40 years. Today, instabilities are regarded as productive and creative sources of change, pattern formation, and growth. They constitute the nomological nucleus of self-organization, chaos and complexity, time's arrow and chance. This change in understanding nature has also modified sciences. Physics has traditionally limited its scope to stability. Currently, it is expanding and renewing itself: a late-modern physics is emerging, and discloses rich interdisciplinary perspectives for the future of mathematical sciences.
Inhaltsangabe:Zusammenfassung: Die Technische Analyse hat sich in vielen Anwendungsbereichen der Finanzmärkte als eine der wichtigsten Analyseinstrumente für die Praxis etabliert. Aufgrund der steigenden Volatilität in vielen Märkten, die gemeinhin als Voraussetzung für die Anwendung der Technischen Analyse gesehen wird, hat die Bedeutung markttechnischer Methoden in den letzten Jahren zugenommen. Daher stellt sich die Frage, welche Konsequenzen mit dem Erfolg der Technischen Analyse im Sinne von wachsender Verbreitung einhergehen. Neben einer systematischen, klassifizierenden Darstellung der wichtigsten Verfahren der Technischen Analyse und einer kurzen Betrachtung ihrer Historie, steht die Betrachtung ihrer Auswirkungen auf Aktienkurse im Mittelpunkt dieser Arbeit. Der Frage nach der Zweckmäßigkeit der Anwendung von Technischer Analyse wird hierbei nicht nachgegangen. Nach einem Überblick der Modelle, die sich mit dieser Fragestellung beschäftigen, soll das Modell von KIRMAN näher vorgestellt werden. Darin wird eine mögliche mathematische Erklärung des Meinungsverbreitungsprozesses geliefert und gezeigt, inwiefern diese für das Entstehen von spekulativen Blasen in einer einfachen Ökonomie verantwortlich ist. In dieser Ökonomie stehen sich Fundamentalanalysten und Technische Analysten gegenüber. Anhand einer Simulation können dann die Effekte der letzteren auf den Kurs einer Aktie analysiert werden.

Kaum eine Industrie wird durch die Digitalisierung so stark geprägt wie der Bankensektor. Neue Technologien verändern die Wertschöpfungskette im Privatkundengeschäft ebenso wie im Firmenkunden- und Kapitalmarktgeschäft. Auch zentrale Funktionen wie Risikomanagement, Finance, Controlling sowie Compliance und Kommunikation müssen sich den Herausforderungen des digitalen Zeitalters stellen. Neben jungen Finanztechnologieunternehmen („FinTechs“) stellen auch Technologie- bzw. Internetkonzerne mit innovativen Lösungen traditionelle Geschäftsmodelle der Finanzdienstleister in Frage. Die erfolgreiche Gestaltung der digitalen Transformation wird somit zum entscheidenden Faktor für eine nachhaltig erfolgreiche Unternehmensentwicklung. Das vorliegende Werk beleuchtet die unterschiedlichen Facetten der Digitalisierung und deren Auswirkungen auf das Bankgeschäft. Dazu gehören die unter dem Stichwort Banking 4.0 dargestellten strategischen Herausforderungen an die Bank der Zukunft angesichts neuer Technologien, veränderter Kundenerwartungen und eines dynamischen Wettbewerbsumfelds. Das Handbuch wurde von führenden Experten und erfahrenen Praktikern verfasst und richtet sich an Fach- und Führungskräfte, die sich mit der Digitalisierung im Bankensektor beschäftigen.

In vielen Disziplinen kontrovers diskutiert, prägt Niklas Luhmanns Systemtheorie die intellektuellen Debatten weit über den universitären Bereich hinaus. Neben einem Einblick in die Biografie Luhmanns zeichnet das Handbuch die Grundlagen seines Denkens und verschiedene Theoriestränge nach. Darunter: Evolutions-, Kommunikations-, Medien- und Gesellschaftstheorie. Detailliert werden einzelne Werke und Werkgruppen besprochen. Weitere Kapitel erklären zentrale Begriffe der Systemtheorie, wie Autopoiesis, Code, Komplexität, System u. v. a.
This book provides a unique insight into the latest breakthroughs in a consistent manner, at a level accessible to undergraduates, yet with enough attention to the theory and computation to satisfy the professional researcher Statistical physics addresses the study and understanding of systems with many degrees of freedom. As such it has a rich and varied history, with applications to thermodynamics, magnetic phase transitions, and order/disorder transformations, to name just a few. However, the tools of statistical physics can be profitably used to investigate any system with a large number of components. Thus, recent years have seen these methods applied in many unexpected directions, three of which are the main focus of this volume. These applications have been remarkably successful and have enriched the financial, biological, and engineering literature. Although reported in the physics literature, the results tend to be scattered and the underlying unity of the field overlooked.
This book aims to provide a comprehensive review of the contribution of network analysis to the understanding of tourism destinations and organizations. Theoretical and methodological aspects are discussed along with a series of applications. While this is a relatively new approach in the tourism literature, in other social and natural sciences network analysis has a long tradition and has provided important insights for the knowledge of the structure and the dynamics of many complex systems. The study of network structures, both from a quantitative and qualitative point of view, can deliver a number of useful outcomes also for the analysis of tourism destinations and organizations.
Robert G. Hagstrom is one of the best-known authors of investment books for general audiences. Turning his extensive experience as a portfolio manager at Legg Mason Capital Management into valuable guidance for professionals and nonprofessionals alike, he is the author of six successful books on investment, including The Warren Buffett Way, a New York Times best-seller that has sold more than a million copies. In this updated second edition of Investing: The Last Liberal Art, Hagstrom explores basic and fundamental investing concepts in a range of fields outside of economics, including physics, biology, sociology, psychology, philosophy, and literature. He discusses, for instance, how the theory of evolution disrupts the notion of the efficient market and how reading strategies for literature can be gainfully applied to investing research. Building on Charlie Munger's famous "latticework of mental models" concept, Hagstrom argues that it is impossible to make good investment decisions based solely on a strong knowledge of finance theory alone. He reinforces his concepts with additional data and a new chapter on mathematics, and updates his text throughout to reflect the developments of the past decade, particularly the seismic economic upheaval of 2008. He has also added a hundred new titles to the invaluable reading list concluding the book. Praise for the first edition: "I read this book in one sitting: I could not put it down."—Peter L. Bernstein, author of Against the Gods: The Remarkable Story of Risk "Elegant and irresistible. Robert G. Hagstrom makes the complex clear as he confidently crisscrosses through the disciplines of finance, biology, physics, and literature. The only way to understand investing better, [Investing] shows, is to understand the world better. Ideas spark off the page at every turn. This is simply a gem of a book."—James Surowiecki, New Yorker "Investing is a brisk and engaging read, and it is a pleasure to be in the presence of Hagstrom's agile mind."—International Herald Tribune
I was invited to join the Organizing Committee of the First International Conference on Complex Sciences: Theory and Applications (Complex 2009) as its ninth member. At that moment, eight distinguished colleagues, General Co-chairs Eugene Stanley and Gaoxi Xiao, Technical Co-chairs János Kertész and Bing-Hong Wang, Local Co-chairs Hengshan Wang and Hong-An Che, Publicity Team Shi Xiao and Yubo Wang, had spent hundreds of hours pushing the conference half way to its birth. Ever since then, I have been amazed to see hundreds of papers flooding in, reviewed and commented on by the TPC members. Finally, more than 200 contributions were - lected for the proceedings currently in your hands. They include about 200 papers from the main conference (selected from more than 320 submissions) and about 33 papers from the five collated workshops: Complexity Theory of Art and Music (COART) Causality in Complex Systems (ComplexCCS) Complex Engineering Networks (ComplexEN) Modeling and Analysis of Human Dynamics (MANDYN) Social Physics and its Applications (SPA) Complex sciences are expanding their colonies at such a dazzling speed that it - comes literally impossible for any conference to cover all the frontiers.
The book is at the level at which a graduate student who has studied condensed matter physics can begin to comprehend the nature of phase transitions, which involve the transformation of one state of matter into another. (A simple example is the melting of a solid to become a liquid.) Such a transformation is termed 'critical' when, after a certain amount of the substance changes phase, the entire bulk virtually instantaneously also makes the transition. A second, updated edition is planned for future publication, but in the mean time this paperback reissue will be useful in teaching the fundamental principles of this extremely interesting subject.

Noise and fluctuations are at the seat of all physical systems. The advertised scope of the conference included gravitational wave detection, quantum fluctuations, quantum Brownian motion, Brownian ratchets, stochastic resonance, biological systems, semiconductors, electronic devices, sandpile physics, optical phenomena and all types of stochastic phenomena. This solicited a wide range of papers from cosmology to biology to electronic devices. Using the study of fluctuations as the unifying theme for these diverse disciplines is a new and exciting concept. UpoN is a unique conference in that it focuses on open questions and problems, rather than answers. 90% of the solution is asking the right question. The discovery of a problem is often more profound than the discovery of a solution. In the spirit of this conference, authors were asked to (1) conclude each manuscript with a section called "Conclusions and Open Questions" and (2) ask questions to the audience at the end of their oral presentation. An important characteristic of this conference is that refereeing of all papers was carried out to a high standard by the International Scientific Advisory Committee using a strict double-blind refereeing process.
