"This book ends with a 'Conclusion' section in which the author gives an excellent, concise summary of the results and issues examined in the volume and lists 'a number of new research problems that can be subject to further scientific and research work' ... I do recommend it for purchase by research libraries, where it will provide a useful reference for those already well versed in the basic elements of nonlinear dynamic systems and those who require a good summary of important recent results in these areas."SIAM Review
