内容简介

  Focusing on applicable rather than applied mathematics, this versatile text is appropriate for advanced undergraduates majoring in any discipline. The author emphasizes basic real analysis as well as differential equations, bringing the concepts of analysis into play wherever possible. Concepts such as norms, metric spaces, completeness, inner products, and asymptotic behavior are introduced within the natural context of solving a problem in differential equations.
  A thorough treatment of linear systems of differential equations inaugurates the text, with a review of necessary concepts from linear algebra and a presentation of basic theory. The constant coefficient cause is examined in detail, and all cases are treated, including that of repeated eigenvalues. The heart of the text develops the ideas of stability and qualitative behavior. Starting with two-dimensional linear systems, the author reviews the use of polar coordinate techniques as well as Liapunov stability and elementary ideas from dynamic systems. Limit cycles appear here as an example of a truly nonlinear phenomenon, and ideas from topology are introduced.
