图书简介
This second edition of Nonstandard Finite Difference Models of Differential Equations provides an update on the progress made in both the theory and application of the NSFD methodology during the past two and a half decades. In addition to discussing details related to the determination of the denominator functions and the nonlocal discrete representations of functions of dependent variables, we include many examples illustrating just how this should be done. Of real value to the reader is the inclusion of a chapter listing many exact difference schemes, and a chapter giving NSFD schemes from the research literature. The book emphasizes the critical roles played by the "principle of dynamic consistency" and the use of sub-equations for the construction of valid NSFD discretizations of differential equations. Key Features: o No other book currently exists on the most recent advances and applications of the NSFD methodology o This book explains directly and clearly, key concepts which are essential for understanding and constructing valid NSFD discretizations of differential equations o Several value-added features include a chapter on explicit representations of exact finite difference schemes for a number of important differential equations and a chapter on applications to a broad range of phenomena in the natural sciences o Also provided is an extensive listing of references to the original research literature
