Taschenbuch. Zustand: Neu. Neuware - Ordinary di erential equations serve as mathematical models for many exciting 'real-world' problems, not only in science and technology, but also in such diverse elds as economics, psychology, defense, and demography. Rapid growth in the theory of di erential equations and in its applications to almost every branch of knowledge has resulted in a continued interest in its study by students in many disciplines. This has given ordinary di er- tial equations a distinct place in mathematics curricula all over the world and it is now being taught at various levels in almost every institution of higher learning. Hundredsofbooksonordinarydi erentialequationsareavailable. H- ever, the majority of these are elementary texts which provide a battery of techniquesfor ndingexplicitsolutions. Thesizeofsomeofthes Elektronisches Buchhas grown dramatically-to the extent that students are often lost in deciding wheretostart. Thisisallduetotheadditionofrepetitiveexamplesand- ercises, and colorful pictures. The advanced books are either on specialized topics or are encyclopedic in character. In fact, there are hardly any rig- ousandperspicuousintroductorytextsavailablewhichcanbeuseddirectly in class for students of applied sciences. Thus, in an e ort to bring the s- ject to a wide audience we provide a compact, but thorough, introduction to the subject in An Introduction to Ordinary Di erential Equations. This book is intended for readers who have had a course in calculus, and hence it canbeusedforaseniorundergraduatecourse. Itshouldalsobesuitablefor a beginning graduate course, because in undergraduate courses, students do not have any exposure to various intricate concepts, perhaps due to an inadequate level of mathematical sophistication.

Taschenbuch. Zustand: Neu. Neuware - Universal Algebra heralded as '. . . the standard reference in a field notorious for the lack of standardization . . .', has become the most authoritative, consistently relied on text in a field with applications in other branches of algebra and other fields such as combinatorics, geometry, and computer science.Each chapter is followed by an extensive list of exercises and problems. The 'state of the art' account also includes new appendices (with contributions from B. Jónsson, R. Quackenbush, W. Taylor, and G. Wenzel) and a well selected additional bibliography of over 1250 papers and books which makes this an indispensable new edition for students, faculty, and workers in the field.'This book will certainly be, in the years to come, the basic reference to the subject.' The American Mathematical Monthly (First Edition)'In this reviewer's opinion [the author] has more than succeeded in his aim. The problems at the end of each chapter are well-chosen; there are more than 650 of them. The book is especially suitable for self-study, as the author frequently provides ample explanation not only of what he is proving, but also of how and why he is proving it. As a reference work for the specialist or a text for the student, the book is highly recommended.' Mathematical Reviews (First Edition)'Since the first day of its appearance in 1968, this book has been the standard reference in universal algebra, and no book since has reached its quality.' Journal of Symbolic Logic (Second Edition).

Buch. Zustand: Neu. Neuware - Conceptualization and measurement of poverty have traditionally relied on purely economic approaches, with income or consumption as the only indicator. Multidimensional approaches have increasingly been used to understand poverty, but have yet to be fully operationalized. This book uses factor analysis and structural equations modelling to develop a multidimensional framework that integrates capability and social inclusion as additional poverty indicators. The empirical relevance of this methodological contribution is demonstrated through its application in the United States and Nepal.The proposed approach not only helps to identify different categories of the poor, but also to more accurately target resources and policies of poverty alleviation. The book will therefore be an important reference for professionals in development agencies as well as for poverty and policy researchers.
