Synergetic System Analysis for the Delay-Induced Hopf Bifurcation in the   Wright Equation
  We apply the synergetic elimination procedure for the stable modes in nonlinear delay systems close to a dynamical instability and derive the normal form for the delay-induced Hopf bifurcation in the Wright equation. The resulting periodic orbit is confirmed by numerical simulations.
