Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This third volume concludes our introduction to analysis, wherein we nish laying the groundwork needed for further study of the subject. As with the rst two, this volume contains more material than can treated in a single course. It is therefore important in preparing lectures to choose a suitable subset of its content; the remainder can be treated in seminars or left to independent study. For a quick overview of this content, consult the table of contents and the chapter introductions. Thisbookisalsosuitableasbackgroundforothercoursesorforselfstudy. We hope that its numerous glimpses into more advanced analysis will arouse curiosity and so invite students to further explore the beauty and scope of this branch of mathematics. In writing this volume, we counted on the invaluable help of friends, c- leagues, sta , and students. Special thanks go to Georg Prokert, Pavol Quittner, Olivier Steiger, and Christoph Walker, who worked through the entire text cr- ically and so helped us remove errors and make substantial improvements. Our thanks also goes out to Carlheinz Kneisel and Bea Wollenmann, who likewise read the majority of the manuscript and pointed out various inconsistencies. Without the inestimable e ortofour 'typesetting perfectionist', this volume could not have reached its present form: her tirelessness and patience with T X E and other software brought not only the end product, but also numerous previous versions,to a high degree of perfection. For this contribution, she has our greatest thanks. 484 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The evolution of the state of many systems modeled by linear partial di erential equations (PDEs) or linear delay di erential equations can be described by ope- torsemigroups.Thestate ofsucha systemis anelementin anin nite-dimensional normed space, whence the name in nite-dimensional linear system . The study of operator semigroups is a mature area of functional analysis, which is still very active. The study of observation and control operators for such semigroups is relatively more recent. These operators are needed to model the - teraction of a system with the surrounding world via outputs or inputs. The main topicsofinterestaboutobservationandcontroloperatorsareadmissibility,obse- ability, controllability, stabilizability and detectability. Observation and control operators are an essential ingredient of well-posed linear systems (or more gen- ally system nodes). In this book we deal only with admissibility, observability and controllability. We deal only with operator semigroups acting on Hilbert spaces. This book is meant to be an elementary introduction into the topics m- tioned above. By elementary we mean that we assume no prior knowledge of nite-dimensional control theory, and no prior knowledge of operator semigroups or of unbounded operators. We introduce everything needed from these areas. We do assume that the reader has a basic understanding of bounded operators on Hilbert spaces, di erential equations, Fourier and Laplace transforms, dist- butions and Sobolev spaces on n-dimensional domains. Much of the background needed in these areas is summarized in the appendices, often with proofs. 496 pp. Englisch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book contributes to important questions in the representation theory of finite groups over fields of positive characteristic - an area of research initiated by Richard Brauer sixty years ago with the introduction of the blocks of characters. On the one hand, it introduces and develops the abstract setting of the Frobenius categories - also called the Saturated fusion systems in the literature - created by the author fifteen years ago for a better understanding of what was loosely called the local theory of a finite group around a prime number p or, later, around a Brauer block, and for the purpose of an eventual classification - a reasonable concept of simple Frobenius category arises.On the other hand, the book develops this abstract setting in parallel with its application to the Brauer blocks, giving the detailed translation of any abstract concept in the particular context of the blocks. One of the new features in this direction is a framework for a deeper understanding of one of the central open problems in modular representation theory, known as Alperin's Weight Conjecture (AWC). Actually, this new framework suggests a more general form of AWC, and a significant result of the book is a reduction theorem of this form of AWC to quasi-simple groups.Although this book is a research monograph, all the arguments are widely developed to make it accessible to the interested graduate students and, at the same time, to put them on the verge of the research on this new subject: the third part of the book on the localities associated to a Frobenius category gives some insight on the open question about the existence and the uniquenes of a perfect locality - also called centric linking system in the literature. We have developed a long introduction to explain our purpose and to provide a guideline for the reader throughout the twenty four sections. A systematic appendix on the cohomology of categories completes the book. 508 pp. Englisch.

Taschenbuch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Ende April und Anfang Mai 2008 kam es in einigen Regionen in Südwestdeutschland zu Bienenvergiftungen, bei denen nach letzten Erhebungen etwa 11.500 Völker von 700 Imkern teilweise erheblich geschädigt wurden. Sofort nach Bekanntwerden der Vorfälle begann eine intensive Suche nach den Ursachen. Dabei arbeiteten das Ministerium für Ernährung und Ländlichen Raum in Baden-Württemberg (MLR) und die Behörden vor Ort mit der Imkerschaft, der Bienenuntersuchungsstelle im Julius Kühn-Institut (JKI), dem Bundesamt für Verbraucherschutz und Lebensmittelsicherheit (BVL) und der Pflanzenschutzmittel-Industrie zusammen. Schnell richtete sich der Verdacht auf Maissaatgut, das mit dem insektiziden Wirkstoff Clothianidin behandelt war, ein Verdacht, der durch die chemischen Analysen des Julius Kühn-Instituts bestätigt wurde. 48 pp. Deutsch.

Buch. Zustand: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This volume focuses on therapeutic targets that were identified after TNF blockade. All these targets have recently been registered or are currently under development for the treatment of rheumatoid arthritis. Each chapter explores the biological rationale of a distinct therapeutic target in great detail. Readers will discover the latest in vitro work, animal models, and results from clinical trials. 228 pp. Englisch.
