• TITLE: Dynamic Analysis of an HTLV-I Infection Model Involving CTL Immune Responses and Immunotaxis

  AUTHORS: Hongyan Kang, Yinji Huang

  KEYWORDS: Immune Chemotaxis, Hopf Bifurcation, Periodic Solutions, Stability

  ABSTRACT: This paper investigates the Hopf bifurcation problem for a class of reaction-diffusion models of HTLV-I infection that incorporate CTL immune responses and immunochemotaxis. Using the chemotaxis coefficient as the bifurcation parameter, this paper derives the conditions for the existence of a Hopf bifurcation at a positive equilibrium point and the existence of periodic solutions. Furthermore, it determines the bifurcation direction and stability of the periodic solutions: if ξ k 0 H ″ ( 0 )>0 , the bifurcation direction is supercritical, and the periodic solution is stable; if ξ k 0 H ″ ( 0 )<0 , the bifurcation direction is subcritical, and the periodic solution is unstable.
