Shangjiang Guo,Jie Li
Keywords:Hopf bifurcation, center manifold theory, normal form theory, Lyapunov- Schmidt reduction, degree theory
Abstract:
      In this paper we survey the topic of bifurcation theory of functionaldifferential equations. We begin with a brief discussion of the position of bifurcationand functional differential equations in dynamical systems. We followwith a survey of the state of the art on the bifurcation theory of functionaldifferential equations, including results on Hopf bifurcation, center manifoldtheory, normal form theory, Lyapunov-Schmidt reduction, and degree theory.
