This book presents a functional approach to the construction, use and approximation of Greenfs functions and their associated ordered exponentials. After a brief historical introduction, the author discusses new solutions to problems involving particle production in crossed laser fields and non-constant electric fields. Applications to problems in potential theory and quantum field theory are covered, along with approximations for the treatment of color fluctuations in high-energy QCD scattering, and a model for summing classes of eikonal graphs in high-energy scattering problems. The book also presents a variant of the Fradkin representation which suggests a new non-perturbative approximation scheme, and provides a qualitative measure of the error involved in each such approximation. Covering the basics as well as more advanced applications, this book is suitable for graduate students and researchers in a wide range of fields, including quantum field theory, fluid dynamics and applied mathematics.

? Describes Greenfs functions, the basis for the modern description of interactions, and their applications

? Contains new solutions to problems involving particle production in crossed laser fields and non-constant electric fields

? A valuable reference text for graduate students and researchers working on causal interactions

Phenomenology, Logic, and the Philosophy of Mathematics

Hardback (ISBN-10: 0521837820 | ISBN-13: 9780521837828)
Published August 2005 | 368 pages | 228 x 152 mm

Offering a collection of fifteen essays that deal with issues at the intersection of phenomenology, logic, and the philosophy of mathematics, this book is divided into three parts. Part I, Reason, Science, and Mathematics contains a general essay on Husserlfs conception of science and logic, an essay of mathematics and transcendental phenomenology, and an essay oN phenomenology and modern pure geometry. Part II is focused on Kurt Godelfs interest in phenomenology. It explores Godelfs ideas and also some work of Quine, Penelope Maddy and Roger Penrose. Part III deals with elementary, constructive areas of mathematics. These are areas of mathematics that are closer to their origins in simple cognitive activities and in everyday experience. This part of the book contains essays on intuitionism, Hermann Weyl, the notion of constructive proof, Poincare and Frege.

? Discusses Kurt Godelfs interest in phenomenology

? Presents new views about the role of intentionality in mathematics and logic

? Up-to-date analyses of phenomenology and the exact sciences

Contents

Part I. Reason, Science, and Mathematics: 1. Science as a triumph of the human spirit and science in crisis: Husserl and the Fortunes of Reason; 2. Mathematics and transcendental phenomenology; Part II. Kurt Godel, Phenomenology and the Philosophy of Mathematics: 3. Kurt Godel and phenomenology; 4. Godelfs philosophical remarks on mathematics and logic; 5. Godelfs path from the incompleteness theorems (1931) to Phenomenology (1961); 6. Godel and the intuition of concepts; 7. Godel and Quine on meaning and mathematics; 8. Maddy on realism in mathematics; 9. Penrose and the view that minds are not machines. Part III. Constructivism, Fulfilled Intentions, and Origins: 10. Intuitionism, meaning theory and cognition; 11. The philosophical background of Weylfs mathematical constructivism; 12. What is a proof?; 13. Phenomenology and mathematical knowledge; 14. Logicism, impredicativity, formalism; 15. The philosophy of arithmetic: Frege and Husserl.

Multivariable Analysis, 2nd Edition
A Practical Guide for Clinicians

Paperback (ISBN-10: 052154985X | ISBN-13: 9780521549851)
Hardback (ISBN-10: 0521840511 | ISBN-13: 9780521840514)

available from January 2006

This new edition has been fully revised to build on the enormous success of its popular predecessor. It now includes new features introduced by readersf requests including a new chapter on propensity score, more detail on clustered data and Poisson regression and a new section on analysis of variance. As before it describes how to perform and interpret multivariable analysis, using plain language rather than complex derivations and mathematical formulae. It is the perfect introduction for all clinical researchers. It focuses on the nuts and bolts of performing research and prepares the reader to perform and interpret multivariable models. Numerous tables, graphs and tips help to simplify and explain the process of performing multivariable analysis. The text is illustrated with many up-to-date examples from the medical literature on how to use multivariable analysis in clinical practice and in research.

? Provides a nonmathematical introduction

? Nuts and bolts practical approach for clinical relevance

? Provides answers to basic questions

Textbook
Lecturers can request inspection copies of this title.
Courses: All biology or life sciences degree courses require students to study statistics in some form. Students will have to take compulsory short introductory statistics courses. This book is ideal for these courses.
Levels: FIRST YEAR UNDERGRADUATE AND UP
Statistics Explained is a reader-friendly introduction to experimental design and statistics for undergraduate students in the life sciences, particularly those who do not have a strong mathematical background. Hypothesis testing and experimental design are discussed first. Statistical tests are then explained using pictorial examples and a minimum of formulae. This class-tested approach, along with a well-structured set of diagnostic tables will give students the confidence to choose an appropriate test with which to analyse their own data sets. Presented in a lively and straight-forward manner, Statistics Explained will give readers the depth and background necessary to proceed to more advanced texts and applications. It will therefore be essential reading for all bioscience undergraduates, and will serve as a useful refresher course for more advanced students.


? Written specifically for life science undergraduates, particularly those without a strong mathematical background

? Extremely clear explanations, using minimal equations and avoiding jargon

? Written by an experienced teacher, and all material has been extensively classroom-tested

Polycyclic Groups (Now in Paperback)

Series: Cambridge Tracts in Mathematics (No. 82)

Paperback (ISBN-10: 0521023947 | ISBN-13: 9780521023948)

There was also a Hardback of this title but it is no longer available
available from November 2005

The theory of polycyclic groups is a branch of infinite group theory which has a rather different flavour from the rest of that subject. This book is a comprehensive account of the present state of this theory. As well as providing a connected and self-contained account of the group-theoretical background, it explains in detail how deep methods of number theory and algebraic group theory have been used to achieve some very recent and rather spectacular advances in the subject. Up to now, most of this material has only been available in scattered research journals, and some of it is new. This book is the only unified account of these developments, and will be of interest to mathematicians doing research in algebra, and to postgraduate students studying that subject.
