An accessible, practical introduction to the principles of differential equations
The field of differential equations is a keystone of scientific knowledge today, with broad applications in mathematics, engineering, physics, and other scientific fields. Encompassing both basic concepts and advanced results, Principles of Differential Equations is the definitive, hands-on introduction professionals and students need in order to gain a strong knowledge base applicable to the many different subfields of differential equations and dynamical systems.

Nelson Markley includes essential background from analysis and linear algebra, in a unified approach to ordinary differential equations that underscores how key theoretical ingredients interconnect. Opening with basic existence and uniqueness results, Principles of Differential Equations systematically illuminates the theory, progressing through linear systems to stable manifolds and bifurcation theory. Other vital topics covered include:

Basic dynamical systems concepts
Constant coefficients
Stability
The Poincare return map
Smooth vector fields
As a comprehensive resource with complete proofs and more than 200 exercises, Principles of Differential Equations is the ideal self-study reference for professionals, and an effective introduction and tutorial for students.

Galois Theory is the algebraic study of groups that can be associated with polynomial equations. This book covers the basic material of Galois theory and discusses many related topics, such as Abelian equations, solvable equations of prime degree, and the casus irreducibilis, that are not mentioned in most standard treatments. It also describes the rich history of Galois theory, including the work of Lagrange, Gauss, Abel, Galois, Jordan, and Kronecker.

Discrete Distributions : Applications in the Health Sciences

ISBN: 0-470-86888-0
Hardcover
312 pages
July 2004

There have been many advances in the theory and applications of discrete distributions in recent years. They can be applied to a wide range of problems, particularly in the health sciences. Discrete Distributions: Applications in the Health Sciences describes a number of new discrete distributions that arise in the statistical examination of real examples. For each example, an understanding of the issues surrounding the data provides the motivation for the subsequent development of the statistical models.
Provides an overview of discrete distributions and their applications in the health sciences.
Focuses on real examples, giving readers an insight into the utility of the models.
Describes the properties of each distribution, and the methods that led to their development.
Presents a range of examples from the health sciences, including cancer, epidemiology, and demography.
Features discussion of software implementation - in SAS, Fortran and R - enabling readers to apply the methods to their own problems.
Written in an accessible style, suitable for applied statisticians and numerate health scientists.
Software and data sets are made available on the Web.
Discrete Distributions: Applications in the Health Sciences provides a practical introduction to these powerful statistical tools and their applications, suitable for researchers and graduate students from statistics and biostatistics. The focus on applications, and the accessible style of the book, make it an excellent practical reference source for practitioners from the health sciences.

Exact Methods in Repeated Measures: MANOVA and Mixed Models

ISBN: 0-471-47017-1
Hardcover
352 pages
August 2004

This book presents some of the most recent developments and classical methods in Multivariate Analysis of Variance (MANOVA), Repeated Measures, and Growth Curves. It attempts to deal with the problem of poor approximations by offering more exact methods for data analysis. Through examples such as following the change in consumer demand of a product over time and analyzing data from clinical trials, Exact Methods in MANOVA, Mixed Models, and Repeated Measures shows readers how these methods are more useful and more accurate in predicting results
