NONLINEAR DIFFERENCE EQUATIONS:
THEORY WITH APPLICATIONS TO
SOCIAL SCIENCE MODELS
A monograph by Hassan
Sedaghat, Mathematics
Professor
Virginia Commonwealth
University, Richmond, Virginia, USA
This book provides rigorous mathematical treatments of models from various social science disciplines. Each section in every chapter ends in a Notes segment which gives additional or related information about the material covered in that section plus some history and complete references. In addition to technical results, the book contains more than 80 diagrams, a large number of examples and counterexamples for motivation and clarification, an extensive bibliography and a detailed index.
Excerpts from reviews by experts in the field:
The Mathematical Reviews: "The level of rigor is substantial ... especially the first part where theorems are stated formally and proofs are given for nearly all of them... final two chapters provide a rich collection of interesting applications from the social sciences, especially economics...These chapters constitute a valuable resource of important applications of discrete dynamical systems." Reviewer: F.R. Marotto, Rev#2004f:39001
Zentralblatt Math: "The reader find both the description and derivation of each model, and its detailed qualitative analysis, which yields a better understanding of the fundamental mechanisms of the real phenomena. The book presents the best known results up to quite recent ones and, in particular, those of the author himself. Besides of the theorems with rigorous proofs it contains many examples, figures, remarks and historical notes. It can be recommended both to researchers and students in mathematics and social sciences." Reviewer: Lothar Berg
The Journal of Difference Equations and Applications: "One of the major strengths of the book is the way Sedaghat has condensed and simplified many of the complex and technical properties of different mathematical social models...Beginning graduate students in mathematics, scientists in the natural or social sciences or mathematicians who want to enter the field of mathematical economics and mathematical [modeling] in the social sciences will find this book useful." Reviewer: A-A. Yakubu, Vol.10, No.10, 2004
