Download or read book Riemannian Geometry During the Second Half of the Twentieth Century written by Marcel Berger and published by American Mathematical Soc.. This book was released on 2000 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: During its first hundred years, Riemannian geometry enjoyed steady, but undistinguished growth as a field of mathematics. In the last fifty years of the twentieth century, however, it has exploded with activity. Berger marks the start of this period with Rauch's pioneering paper of 1951, which contains the first real pinching theorem and an amazing leap in the depth of the connection between geometry and topology. Since then, the field has become so rich that it is almost impossible for the uninitiated to find their way through it. Textbooks on the subject invariably must choose a particular approach, thus narrowing the path. In this book, Berger provides a remarkable survey of the main developments in Riemannian geometry in the second half of the last fifty years. One of the most powerful features of Riemannian manifolds is that they have invariants of (at least) three different kinds. There are the geometric invariants: topology, the metric, various notions of curvature, and relationships among these. There are analytic invariants: eigenvalues of the Laplacian, wave equations, Schrödinger equations. There are the invariants that come from Hamiltonian mechanics: geodesic flow, ergodic properties, periodic geodesics. Finally, there are important results relating different types of invariants. To keep the size of this survey manageable, Berger focuses on five areas of Riemannian geometry: Curvature and topology; the construction of and the classification of space forms; distinguished metrics, especially Einstein metrics; eigenvalues and eigenfunctions of the Laplacian; the study of periodic geodesics and the geodesic flow. Other topics are treated in less detail in a separate section. While Berger's survey is not intended for the complete beginner (one should already be familiar with notions of curvature and geodesics), he provides a detailed map to the major developments of Riemannian geometry from 1950 to 1999. Important threads are highlighted, with brief descriptions of the results that make up that thread. This supremely scholarly account is remarkable for its careful citations and voluminous bibliography. If you wish to learn about the results that have defined Riemannian geometry in the last half century, start with this book.

Available in PDF, EPUB and Kindle. Book excerpt: 'One day there is life . . . and then, suddenly, it happens there is death.' So begins Paul Auster's moving and personal meditation on fatherhood. The first section, 'Portrait of an Invisible Man', reveals Auster's memories and feelings after the death of his father. In 'The Book of Memory' the perspective shifts to Auster's role as a father. The narrator, 'A', contemplates his separation from his son, his dying grandfather and the solitary nature of writing and story-telling.

Download or read book Ethical and Social Issues in the Information Age written by Joseph M. Kizza and published by Springer Science & Business Media. This book was released on 2007-06-02 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook provides an introduction to the social and policy issues which have arisen as a result of information technology. Whilst it assumes a modest familiarity with computers, its aim is to provide a guide to the issues suitable for undergraduates. In doing so, the author prompts the students to consider questions such as: "What are the moral codes of cyberspace?" Throughout, the book shows how in many ways the technological development is outpacing the ability of our legal systems to keep up, and how different paradigms applied to ethical questions may often offer conflicting conclusions. As a result students will find this to be a thought-provoking and valuable survey.
Download or read book Dar Al Islam the Mediterranean the World System and the Wider Europe written by Peter Herrmann and published by Nova Publishers. This book was released on 2005 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the process of a 'wider Europe' (EU-Commission President Romano Prodi's 'ring of friends') that extends from Marrakech in Morocco to St Petersburg in Russia gathering speed, the growing rift between Europe and America also is about how to deal politically with the countries of the Mediterranean-Muslim world. The house of Islam (Dar al Islam) was pivotal to the European path to the Renaissance and to the re-discovery of classic Greek philosophy. The Mediterranean policy of the European Union aims at a positive and co-operative relationship with the region. A successful integration of the Mediterranean South would have tremendous and positive repercussions for regional and world peace. World-wide leading experts from the field of world systems analysis, economics, integration theory, political science, theology and area studies, agnostics, Christians, Jews and Muslims alike discuss the issue with European decision makers. The outcome is an interdisciplinary evaluation of this projected export of peace, co-operation, dialogue and stability in the framework of world centre-periphery relationships.

Download or read book Ein Leben F r Die Wissenschaft written by Salomo A. Birnbaum and published by Walter de Gruyter. This book was released on 2011 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Salomo A. Birnbaum (1891-1989) ist unbestrittener Pionier auf zwei großen, eng aufeinander bezogenen Forschungsgebieten, nämlich der historischen jiddischen Sprachwissenschaft sowie der Paläographie des Hebräischen und aller jüdischen Nachfolgesprachen: 1918 veröffentlichte er die erste wissenschaftliche Grammatik des Jiddischen (vier weitere Auflagen ab 1966); in den 20er Jahren begann er - ausgehend von dem Bedürfnis, mittelalterliche jiddische Manuskripte zu datieren und zu lokalisieren - mit seinen paläographischen Studien, die in dem Standardwerk The Hebrew Scripts (1954/57-1971) gipfelten und ihm zugleich ein weiteres Forschungsgebiet, die Vergleichung jüdischer Sprachen, eröffneten. Die vorliegende Aufsatzsammlung (teils Wiederabdrucke, teils nach bisher ungedruckten Manuskripten ediert) bildet nach Birnbaums eigenen Vorstellungen einen Querschnitt durch sein Lebenswerk. Bd. I enthält Beiträge zur jiddischen Philologie: Entstehung und Alter der Sprache, orthographische und lautliche Entwicklungen, Probleme der Umsetzung in Lateinschrift, Dialektologie, Etymologie u.a., ferner einen Überblick über die weiteren jüdischen Sprachen sowie umfangreiche Einzeluntersuchungen insbesondere zum Dzudezmo ('Jüdischspanischen') und zum Bucharischen ('Jüdischpersischen'). Die Beiträge in Bd. II dokumentieren die Entwicklung der sich etablierenden hebräischen Paläographie in den 30er bis 60er Jahren, wo Birnbaums quantitative und vergleichende Methoden sich vor allem seit 1947 an den damals aufgefundenen Schriftrollen vom Toten Meer, aber auch an Neufunden mittelalterlicher jiddischer Handschriften glänzend bewährten. Birnbaum lehrte von 1922 bis 1933 Jiddisch an der Universität Hamburg, von 1936 bis 1957 Jiddisch und hebräische Paläographie an Londoner universitären Instituten.

Download or read book Climate Change and Ancient Societies in Europe and the Near East written by Paul Erdkamp and published by Springer Nature. This book was released on 2021-11-05 with total page 669 pages. Available in PDF, EPUB and Kindle. Book excerpt: Climate change over the past thousands of years is undeniable, but debate has arisen about its impact on past human societies. This book explores the link between climate and society in ancient worlds, focusing on the ancient economies of western Eurasia and northern Africa from the fourth millennium BCE up to the end of the first millennium CE. This book contributes to the multi-disciplinary debate between scholars working on climate and society from various backgrounds. The chronological boundaries of the book are set by the emergence of complex societies in the Neolithic on the one end and the rise of early-modern states in global political and economic exchange on the other. In order to stimulate comparison across the boundaries of modern periodization, this book ends with demography and climate change in early-modern and modern Italy, a society whose empirical data allows the kind of statistical analysis that is impossible for ancient societies. The book highlights the role of human agency, and the complex interactions between the natural environment and the socio-cultural, political, demographic, and economic infrastructure of any given society. It is intended for a wide audience of scholars and students in ancient economic history, specifically Rome and Late Antiquity.
