Differential Equations and Numerical Analysis

This book offers an ideal introduction to singular perturbation problems, and a valuable guide for researchers in the field of differential equations. It also includes chapters on new contributions to both fields: differential equations and singular perturbation problems. Written by experts who are active researchers in the related fields, the book serves as a comprehensive source of information on the underlying ideas in the construction of numerical methods to address different classes of problems with solutions of different behaviors, which will ultimately help researchers to design and assess numerical methods for solving new problems. All the chapters presented in the volume are complemented by illustrations in the form of tables and graphs.

Describes recent developments in the field of research on differential equations Shows researchers how to design and analyze numerical methods for solving new problems Helps readers construct numerical methods to address different classes of problems with solutions of different behaviors Includes supplementary material: sn.pub/extras
