Introduction to cryptography principles and applications by Hans Delfs ( )
24 editions published between 2002 and 2010 in English and held by 835 WorldCat member libraries worldwide
"In the first part, this book covers the key concepts of cryptography on an undergraduate level, from encryption and digital signatures to cryptographic protocols. Essential techniques are demonstrated in protocols for key exchange, user identification, electronic elections and digital cash. In the second part, more advanced topics are addressed, such as the bit security of one-way functions and computationally perfect pseudorandom bit generators. The security of cryptographic schemes is a central topic. Typical examples of provably secure encryption and signature schemes and their security proofs are given. Though particular attention is given to the mathematical foundations, no special background in mathematics is presumed. The necessary algebra, number theory and probability theory are included in the appendix. Each chapter closes with a collection of exercises."--Jacket
Locally semialgebraic spaces by Hans Delfs ( Book )
14 editions published in 1985 in English and German and held by 464 WorldCat member libraries worldwide
Homology of locally semialgebraic spaces by Hans Delfs ( Book )
14 editions published in 1991 in English and held by 436 WorldCat member libraries worldwide
Locally semialgebraic spaces serve as an appropriate framework for studying the topological properties of varieties and semialgebraic sets over a real closed field. This book contributes to the fundamental theory of semialgebraic topology and falls into two main parts. The first dealswith sheaves and their cohomology on spaces which locally look like a constructible subset of a real spectrum. Topics like families of support, homotopy, acyclic sheaves, base-change theorems and cohomological dimension are considered. In the second part a homology theory for locally complete locally semialgebraic spaces over a real closed field is developed, the semialgebraic analogue of classical Bore-Moore-homology. Topics include fundamental classes of manifolds and varieties, Poincare duality, extensions of the base field and a comparison with the classical theory. Applying semialgebraic Borel-Moore-homology, a semialgebraic ("topological") approach to intersection theory on varieties over an algebraically closed field of characteristic zero is given. The book is addressed to researchers and advanced students in real algebraic geometry and related areas

Summary: Diese Briefedition gibt einen umfassenden Einblick in Ernst Ludwig Kirchners Leben und Schaffen, eröffnet einen Zugang zu dem, was ihn bewegte und umtrieb. Es macht betroffen, wie er seine besten Freunde tief verletzen konnte, wir sehen verblüfft, wie er mit der Wahrheit umging, seine persönliche Realität nach Bedarf ständig neu erschuf und wie er Adressaten und Öffentlichkeit manipulierte. Die Briefe und Briefentwürfe werden in chronologischer Reihenfolge und in der originalen Schreibweise mit den Federskizzen im Text wiedergegeben. Der Register-Band umfasst ca. 30000 Verweise, gegliedert in Sachregister, Register der erwähnten Personen, der Kunstwerke, der Ausstellungen und der Literatur
