Geomathematics provides a comprehensive summary of the mathematical principles behind key topics in geophysics and geodesy, covering the foundations of gravimetry, geomagnetics and seismology. Theorems and their proofs explain why physical realities in geoscience are the logical mathematical consequences of basic laws. The book also derives and analyzes the theory and numerical aspects of established systems of basis functions; and presents an algorithm for combining different types of trial functions. Topics cover inverse problems and their regularization, the Laplace/Poisson equation, boundary-value problems, foundations of potential theory, the Poisson integral formula, spherical harmonics, Legendre polynomials and functions, radial basis functions, the Biot-Savart law, decomposition theorems (orthogonal, Helmholtz, and Mie), basics of continuum mechanics, conservation laws, modelling of seismic waves, the Cauchy-Navier equation, seismic rays, and travel-time tomography. Each chapter ends with review questions, with solutions for instructors available online, providing a valuable reference for graduate students and researchers.

Dieses Lehrbuch über die Lineare Algebra deckt den gesamten Stoff der zweisemestrigen Grundvorlesung ab. Seine anschauliche und konsequent matrizenorientierte Herangehensweise ermöglicht Studierenden ein intuitives Verständnis der abstrakten Objekte. Die im Buch präsentierten vielfältigen Anwendungen und Beispiele motivieren Studierende zur intensiven Auseinandersetzung mit der Linearen Algebra als leistungsfähiges mathematisches Werkzeug. In vielen „MATLAB-Minuten“ können sich Studierende wichtige Sätze und Konzepte am Rechner erarbeiten. Alle notwendigen Vorkenntnisse werden in einer MATLAB-Kurzeinführung erläutert. Das Buch enthält zudem über 350 Übungsaufgaben, die das Erlernen des Stoffes unterstützen. Interessierte Studierende finden darüber hinaus historische Notizen zur Entwicklung des Gebiets. Für diese dritte Auflage wurde die zweite Auflage durchgesehen und ergänzt. Zu den Ergänzungen gehören Abschnitte über die vollständige Induktion und die Existenz von Basen und von Adjungierten in unendlichdimensionalen Vektorräumen. Der übersichtliche Aufbau und das bewährte Konzept des Lehrbuchs wurden beibehalten.

Where along the Rhine does the Nibelung Treasure lie? What river helps mark the prime meridian? Why do people make pilgrimages to the Indian city of Benares? Why is the Mekong called the “Nine Dragon” river in Vietnam? How does the Mississippi divide and unite the United States? These and hundreds of other facts are explored in this wonderfully illustrated atlas of the world’s great rivers. Each spread in this book, which includes a gorgeous gatefold page, offers a colorful map packed with drawings, figures, and facts. Cities that border the rivers are highlighted, as are distinct flora and fauna, significant natural and human- made features, and fascinating historical details. A “biography” of each river describes where it flows, and its importance to the communities it passes through. Special attention is given to the ecological health of the rivers—those that are thriving and those in danger of losing their valuable habitats. Along the way, young readers will come to understand the enormous impact that rivers have on our lives, while learning valuable information in a way that will spark their curiosity and imagination.

This book, one of three volumes, showcases the effective transformation of companies providing banking and insurance services. This first volume gives a business-oriented introduction to the setting and the current challenges of fintech, regtech, and insurtech and provides an outlook on what will be needed in the future. Specific sub-departments in financial services are examined with a view to accounting, risk, and regulatory segments. The book also addresses the importance of cultural aspects of the coming digital transformation with an eye to requirements that will enable a digital bank or insurance company to thrive in 2025. The angle shifts over the volumes from a business-driven approach in “Disruption and DNA” to a strong technical focus in “Data Storage, Processing and Analysis”, leaving “Digitalization and Machine Learning Applications” with the business and technical aspects in-between.

This book, the second one of three volumes, gives practical examples by a number of use cases showing how to take first steps in the digital journey of banks and insurance companies. The angle shifts over the volumes from a business-driven approach in “Disruption and DNA” to a strong technical focus in “Data Storage, Processing and Analysis”, leaving “Digitalization and Machine Learning Applications” with the business and technical aspects in-between. This second volume mainly emphasizes use cases as well as the methods and technologies applied to drive digital transformation (such as processes, leveraging computational power and machine learning models).
