Web10 and a Hopf bifurcation occurs when t 1 =t 10. 3. STABILITY AND DIRECTION OF HOPF BIFURCATION The objective of this section is to determine the direction of Hopf bifurcation and analyze the stability of periodic solutions. To achieve this objective, we will apply the theory of normal form and the center manifold theorem to our system. WebC, a supercritical Hopf bifurcation takes place for the upper branch steady state (Lebovitz [5]). We aim to show analytically what has been shown numerically. To do so, we employ …
