Heights in Diophantine Geometry

Series: New Mathematical Monographs
Hardback (ISBN-10: 0521846153 | ISBN-13: 9780521846158)

Diophantine geometry has been studied by number theorists for thousands of years, since the time of Pythagoras, and has continued to be a rich area of ideas such as Fermat's Last Theorem, and most recently the ABC conjecture. This monograph is a bridge between the classical theory and modern approach via arithmetic geometry. The authors provide a clear path through the subject for graduate students and researchers. They have re-examined many results and much of the literature, and give a thorough account of several topics at a level not seen before in book form. The treatment is largely self-contained, with proofs given in full detail. Many results appear here for the first time. The book concludes with a comprehensive bibliography. It is destined to be a definitive reference on modern diophantine geometry, bringing a new standard of rigor and elegance to the field.

Courses: Computational Complexity Complexity Theory Cryptography
Levels: FINAL YEAR UNDERGRADUATE/MSC
Cryptography plays a crucial role in many aspects of today's world, from internet banking and ecommerce to email and web-based business processes. Understanding the principles on which it is based is an important topic that requires a knowledge of both computational complexity and a range of topics in pure mathematics. This book provides that knowledge, combining an informal style with rigorous proofs of the key results to give an accessible introduction. It comes with plenty of examples and exercises (many with hints and solutions), and is based on a highly successful course developed and taught over many years to undergraduate and graduate students in mathematics and computer science.

* The first introductory textbook combining the topics of Computational Complexity with Cryptography

* Self-contained - the Appendices contain all the required mathematics

* Over 160 exercises and problems, many with hints and solutions

Lagrangian Fluid Dynamics

Series: Cambridge Monographs on Mechanics
Hardback (ISBN-10: 0521853109 | ISBN-13: 9780521853101)
Not yet published - available from January 2006

The emergence of observing systems such as acoustically-tracked floats in the deep ocean, and surface drifters navigating by satellite has seen renewed interest in Lagrangian fluid dynamics. Starting from the foundations of elementary kinematics and assuming some familiarity of Eulerian fluid dynamics, this book reviews the classical and new exact solutions of the Lagrangian framework, and then addresses the general solvability of the resulting general equations of motion. A unified account of turbulent diffusion and dispersion is offered, with applications among others to plankton patchiness in the ocean. Written at graduate level, the book provides the first detailed and comprehensive analytical development of the Lagrangian formulation of fluid dynamics, of interest not only to applied mathematicians but also oceanographers, meteorologists, mechanical engineers, astrophysicists and indeed all investigators of the dynamics of fluids.

* The first book that gives a unified account of Lagrangian fluid dynamics

* Well-respected and experienced author in the fields of oceanography and mathematics

* Written at graduate level and can be used as an academic reference for oceanographers, meteorologists, mechanical engineers, astrophysicists or all investigators of the dynamics of fluids

Fractional Cauchy Transforms

Series: Monographs & Surveys in Pure & Applied Math Volume: 136
ISBN: 1584885602
Publication Date: 11/1/2005
Number of Pages: 272

Presents an organized, accessible introduction to fractional Cauchy transforms
Includes new, previously unpublished research
Provides background and related earlier results about Cauchy transforms, giving a full perspective of the field
Features sources for results with additional references and comments

Presenting new results along with research spanning five decades, Fractional Cauchy Transforms provides a full treatment of the topic, from its roots in classical complex analysis to its current state. Self-contained, it includes introductory material and classical results, such as those associated with complex-valued measures on the unit circle, that form the basis of the developments that follow. The authors focus on concrete analytic questions, with functional analysis providing the general framework.

After examining basic properties, the authors study integral means and relationships between the fractional Cauchy transforms and the Hardy and Dirichlet spaces. They then study radial and nontangential limits, followed by chapters devoted to multipliers, composition operators, and univalent functions. The final chapter gives an analytic characterization of the family of Cauchy transforms when considered as functions defined in the complement of the unit circle.
