Pure and Applied Mathematics: A Wiley-Interscience Series of #89: An Introduction to Nonlinear Partial Differential Equationsby J. David Logan
Synopses & Reviews
Praise for the First Edition:
"This book is well conceived and well written. The author has succeeded in producing a text on nonlinear PDEs that is not only quite readable but also accessible to students from diverse backgrounds."
A practical introduction to nonlinear PDEs and their real-world applications
Now in a Second Edition, this popular book on nonlinear partial differential equations (PDEs) contains expanded coverage on the central topics of applied mathematics in an elementary, highly readable format and is accessible to students and researchers in the field of pure and applied mathematics. This book provides a new focus on the increasing use of mathematical applications in the life sciences, while also addressing key topics such as linear PDEs, first-order nonlinear PDEs, classical and weak solutions, shocks, hyperbolic systems, nonlinear diffusion, and elliptic equations. Unlike comparable books that typically only use formal proofs and theory to demonstrate results, An Introduction to Nonlinear Partial Differential Equations, Second Edition takes a more practical approach to nonlinear PDEs by emphasizing how the results are used, why they are important, and how they are applied to real problems.
The intertwining relationship between mathematics and physical phenomena is discovered using detailed examples of applications across various areas such as biology, combustion, traffic flow, heat transfer, fluid mechanics, quantum mechanics, and the chemical reactor theory. New features of the Second Edition also include:
With individual, self-contained chapters and a broad scope of coverage that offers instructors the flexibility to design courses to meet specific objectives, An Introduction to Nonlinear Partial Differential Equations, Second Edition is an ideal text for applied mathematics courses at the upper-undergraduate and graduate levels. It also serves as a valuable resource for researchers and professionals in the fields of mathematics, biology, engineering, and physics who would like to further their knowledge of PDEs.
Book News Annotation:
Updated to include expanded coverage of applied mathematics, this edition continues to provide a solid introduction for students and researchers, including those studying or practicing in the life sciences with such topics as age-structure, pattern formation, and the propagation of diseases. Logan (mathematics, U. of Nebraska-Lincoln) keeps the text accessible by emphasizing how the results are used, why they are important and how they are applied to real problems rather than using only formal proofs and theory. After a thorough introduction he explains first-order equations and characteristics, weak solutions to hyperbolic equations, hyperbolic systems, and diffusion processes, providing details on other topics such as reaction-diffusion systems and equilibrium models in an integrated appendix on dynamical systems. Instructors will find the self-contained chapters ideal for customized curriculum design. Annotation ©2008 Book News, Inc., Portland, OR (booknews.com)
'This introductory textbook on nonlinear partial differential equations is technique oriented with an emphasis on applications and is designed to build a foundation for studying advanced treatises in the field. The Second Edition features an updated bibliography as well as an increase in the number of exercises. All software references have been updated with the latest version of MATLAB®, the the corresponding graphics have also been updated using MATLAB®. An increased focus on hydrogeology and mathematical biology is evident in the new edition. Hints and solutions to selected exercises have been added to the back of the book. The book emphasizes hyperbolic and parabolic problems and includes a range of applications in the following areas: biology, chemistry, porous media, biological problems, combustion and detonation, traffic flow, water waves, plug flow reactors, and heat transfer. Early chapters offer insight into how to understand problems involving phenomena, how specific equations describe evolutionary processes, and what the terms in such equations describe physically. When discussing wave propagination and hyperbolic problems, the text develops algorithms to solve first-order equations and highlights the concept of the weak solution. The material in the book is presented in such a manner that many of the chapters are independent, which allows for instructors flexibility to design several courses around various topics. '
