Chapter 4 includes a detailed normal form analysis of the Neimark-Sacker bifur- cation. linear algebra, analysis, and differential equations is required. A brief summary of general mathematical terms and results, which are assumed to be known in the main text, appears at the end of the. and iterated maps is given, and the geometry of the phase portrait near such points is studied. A bifurcation diagram of a parameter-dependent system is introduced as a partitioning of its parameter
