”MUA 214 existerade inte. Någon hade gått in i den militära underrättelsetjänstens skyddade datasystem och skapat ett falskt ID-nummer för att godkänna Anna Löwenskölds säkerhetsprövning. Men vem, och varför?” När Alice Rosengren på Säkerhetskontorets kontraspionage avslöjar en misstänkt rysk infiltratör finner hon sig plötsligt motarbetad. Någon läcker hennes identitet och snart utsätts hon för en brutal påverkanskampanj med syfte att bryta ner både hennes person och hennes trovärdighet. I den kamp som följer ställs både rikets säkerhet och Alices egen familj på spel. Frågan är inte när Ryssland infiltrerar, frågan är hur mycket skada de redan har orsakat. En häpnadsväckande och klaustrofobisk thriller som bygger på ett verkligt fall inom svensk underrättelsetjänst.
The goal of these notes is to provide a fast introduction to symplectic geometry for graduate students with some knowledge of differential geometry, de Rham theory and classical Lie groups. This text addresses symplectomorphisms, local forms, contact manifolds, compatible almost complex structures, Kaehler manifolds, hamiltonian mechanics, moment maps, symplectic reduction and symplectic toric manifolds. It contains guided problems, called homework, designed to complement the exposition or extend the reader's understanding. There are by now excellent references on symplectic geometry, a subset of which is in the bibliography of this book. However, the most efficient introduction to a subject is often a short elementary treatment, and these notes attempt to serve that purpose. This text provides a taste of areas of current research and will prepare the reader to explore recent papers and extensive books on symplectic geometry where the pace is much faster. For this reprint numerous corrections and clarifications have been made, and the layout has been improved.
This volume is concerned with a detailed description of the canonical operator method - one of the asymptotic methods of linear mathematical physics. The book is, in fact, an extension and continuation of the authors' works [59], [60], [65]. The basic ideas are summarized in the Introduction. The book consists of two parts. In the first, the theory of the canonical operator is develop ed, whereas, in the second, many applications of the canonical operator method to concrete problems of mathematical physics are presented. The authors are pleased to express their deep gratitude to S. M. Tsidilin for his valuable comments. THE AUTHORS IX INTRODUCTION 1. Various problems of mathematical and theo...
An introductory 1997 account in the style of the original discoverers, treating the fundamental themes even-handedly.
What is the true mark of inspiration? Ideally it may mean the originality, freshness and enthusiasm of a new breakthrough in mathematical thought. The reader will feel this inspiration in all four seminal papers by Duistermaat, Guillemin and Hörmander presented here for the first time ever in one volume. However, as time goes by, the price researchers have to pay is to sacrifice simplicity for the sake of a higher degree of abstraction. Thus the original idea will only be a foundation on which more and more abstract theories are being built. It is the unique feature of this book to combine the basic motivations and ideas of the early sources with knowledgeable and lucid expositions on the present state of Fourier Integral Operators, thus bridging the gap between the past and present. A handy and useful introduction that will serve novices in this field and working mathematicians equally well.
