Appropriate for advanced undergraduate and graduate students in a variety of scientific and engineering fields, this text introduces linear and nonlinear problems and their associated models. The first part covers linear systems, emphasizing perturbation or approximation techniques and asymptotic methods. The second part comprises nonlinear problems, including weakly nonlinear oscillatory systems and nonlinear difference equations. The two parts, both of which include exercises, merge smoothly, and many of the nonlinear techniques arise from the study of the linear systems. 1990 edition. 70 figures. 4 tables. Appendix. Index.
Part I of this text/reference presents techniques for linear systems with emphasis on asymptotic methods. The development in Part II employs the methods given in the first part and focuses attention on weakly nonlinear oscillatory systems and nonlinear difference equations. The stress is on practical methods, rather than on proof of theorems, and each method is illustrated by examples of applications in the sciences. Presents some numerical and graphical solutions generated by Lotus 1-2-3 and Math CAD.
