Texts in Applied Mathematics. 7. New York, NY: Springer. xiv, 519 p. (1996).

The first edition (1991) has been reviewed in Zbl 0717.34001. From the preface to the second edition: “Several new sections have been added in the second edition of this book. Sections 2.12 and 2.13 on center manifold theory and normal forms which generalize the material in Section 2.11 for planar systems, are new. A more detailed development of Melnikov’s method, including some new theorems and their proofs and a new section on higher-order Melnikov theory, is given in Chapter 4. A discussion of the codimension and the universal unfolding of a bifurcation as well as some examples of higher codimension bifurcation, such as the Takens-Bogdanov bifurcation, have also been added in Chapter 4. The book ends with a new section on one of the author’s favorite research topics, a study of the bifurcations that occur in the class of bounded quadratic systems. The student is encouraged to participate in this research project by determining the bifurcation surfaces that occur in the class of bounded quadratic systems in the problem set at the end of Chapter 4”.
