E. M. Wright - Böcker

An Introduction to the Theory of Numbers by G.H. Hardy and E. M. Wright is found on the reading list of virtually all elementary number theory courses and is widely regarded as the primary and classic text in elementary number theory. Developed under the guidance of D.R. Heath-Brown this Sixth Edition of An Introduction to the Theory of Numbers has been extensively revised and updated to guide today's students through the key milestones and developments in number theory. Updates include a chapter by J.H. Silverman on one of the most important developments in number theory -- modular elliptic curves and their role in the proof of Fermat's Last Theorem -- a foreword by A. Wiles, and comprehensively updated end-of-chapter notes detailing the key developments in number theory. Suggestions for further reading are also included for the more avid readerThe text retains the style and clarity of previous editions making it highly suitable for undergraduates in mathematics from the first year upwards as well as an essential reference for all number theorists.

In this second special issue on signal transductionleading specialists in their fields again present overviewsof topics related to the highly topicalsubject of signaltransduction. The first contribution, by Keppler, deals withthe biosynthesis, transport, inactivation, and analysis ofleukotrienes. Mohr et al. present an excellent overview ofthe biology of the peptide hormone oxytocin and its role insignal transduction.The review by Holzer describes thesignificance of peptinergic sensory neurons in the controlof vascular functions. In the contribution by Wolf etalthe molecular biology of the Y chromosome is discussed.
